00:00:12,753 --> 00:00:16,491
The drive through the world's
most secure prison is beautiful.

2
00:00:16,515 --> 00:00:20,468
The federal government's
only supermax prison, known as ADX,

3
00:00:20,492 --> 00:00:22,625
is 90 miles south of Denver.

4
00:00:22,649 --> 00:00:24,498
Standing outside the building,

5
00:00:24,522 --> 00:00:27,625
ADX looks like a newish
suburban middle school.

6
00:00:27,649 --> 00:00:29,268
(Laughter)

7
00:00:29,292 --> 00:00:31,903
The lobby is clean and bright;

8
00:00:31,927 --> 00:00:35,125
there's big windows
and clear views of the mountains;

9
00:00:35,149 --> 00:00:39,323
and a polite front-desk attendant
with a kiosk selling travel mugs.

10
00:00:39,347 --> 00:00:41,268
(Laughter)

11
00:00:41,292 --> 00:00:43,910
On the wall is a large plaque that reads,

12
00:00:43,934 --> 00:00:47,014
"The best prize that life offers
is the chance to work hard

13
00:00:47,038 --> 00:00:48,438
at work worth doing."

14
00:00:49,427 --> 00:00:52,693
Just past it is a huge
framed photo of Alcatraz.

15
00:00:53,911 --> 00:00:57,037
And down the stairs,
at the end of a long hallway,

16
00:00:57,061 --> 00:01:00,355
are 400 men decaying in isolation cells.

17
00:01:01,792 --> 00:01:05,686
I work on cases involving
the constitutional rights of prisoners.

18
00:01:05,710 --> 00:01:09,066
Now, people have differing views
about prisoners' rights.

19
00:01:09,511 --> 00:01:11,940
But there's something
more people can agree on:

20
00:01:11,964 --> 00:01:13,114
torture.

21
00:01:14,130 --> 00:01:16,337
The US government
says it doesn't use torture,

22
00:01:16,361 --> 00:01:19,101
and we condemn other countries,
like Iran and North Korea,

23
00:01:19,125 --> 00:01:20,792
for their use of torture.

24
00:01:21,496 --> 00:01:25,410
But some people think the so-called
worst of the worst deserve it:

25
00:01:25,434 --> 00:01:29,355
terrorists, mass murderers,
the really "bad" people.

26
00:01:30,071 --> 00:01:32,969
Now I personally believe
that no one deserves to be tortured

27
00:01:32,993 --> 00:01:34,317
by the US government.

28
00:01:34,341 --> 00:01:35,599
But that's me.

29
00:01:35,623 --> 00:01:42,623
(Applause)

30
00:01:42,647 --> 00:01:43,853
No matter where you fall,

31
00:01:43,877 --> 00:01:46,059
there's a few things
I need you to understand

32
00:01:46,083 --> 00:01:47,283
before I continue.

33
00:01:47,869 --> 00:01:50,537
First, we do torture people
here in America,

34
00:01:50,561 --> 00:01:52,903
tens of thousands of them every day.

35
00:01:52,927 --> 00:01:55,127
It's called solitary confinement.

36
00:01:55,513 --> 00:01:57,823
It's done in our names,
using our tax dollars,

37
00:01:57,847 --> 00:01:59,386
behind closed doors.

38
00:01:59,902 --> 00:02:01,260
And as a result,

39
00:02:01,284 --> 00:02:04,427
we're undermining the core values
of our justice system.

40
00:02:05,477 --> 00:02:07,367
Built with state-of-the-art technology,

41
00:02:07,391 --> 00:02:10,297
ADX has nearly perfected
solitary confinement.

42
00:02:10,970 --> 00:02:13,038
Each man spends 23 hours a day

43
00:02:13,062 --> 00:02:15,924
alone in a cell
the size of a small bathroom.

44
00:02:16,537 --> 00:02:20,109
Virtually every aspect of his life
occurs in that cell.

45
00:02:20,133 --> 00:02:22,403
But aside from sleeping and eating,

46
00:02:22,427 --> 00:02:25,141
which he does within
an arm's reach of his toilet,

47
00:02:25,165 --> 00:02:27,061
there aren't many aspects of life.

48
00:02:27,680 --> 00:02:31,714
Correctional officers push food trays
through slots in the doors

49
00:02:31,738 --> 00:02:34,175
and take the men
to solitary exercise cages

50
00:02:34,199 --> 00:02:36,794
that are referred to
by prisoners and staff alike,

51
00:02:36,818 --> 00:02:39,128
without irony, as dog runs.

52
00:02:39,992 --> 00:02:41,387
Other than that,

53
00:02:41,411 --> 00:02:43,418
these men are locked in cement closets,

54
00:02:43,442 --> 00:02:45,243
all day, every day.

55
00:02:45,577 --> 00:02:47,903
Two steps forward, two steps back.

56
00:02:47,927 --> 00:02:49,077
That's it.

57
00:02:49,673 --> 00:02:52,665
They can't see the nearby
mountains or any trees --

58
00:02:52,689 --> 00:02:55,395
"nothing living, not so much
as a blade of grass,"

59
00:02:55,419 --> 00:02:57,752
is how one man in ADX described it.

60
00:02:58,435 --> 00:03:01,542
Some people report that after years
of not looking at anything

61
00:03:01,566 --> 00:03:03,288
further than 10 feet away,

62
00:03:03,312 --> 00:03:05,287
their eyesight has deteriorated so much

63
00:03:05,311 --> 00:03:08,160
that they can't focus
on faraway objects anymore.

64
00:03:08,748 --> 00:03:10,895
The isolation is so deep and profound

65
00:03:10,919 --> 00:03:14,799
that one of our clients would lie
on the floor of his cell for hours,

66
00:03:14,823 --> 00:03:17,078
just hoping to catch a glimpse
of someone's feet

67
00:03:17,102 --> 00:03:19,402
as they walked past the door of his cell.

68
00:03:19,924 --> 00:03:22,948
Another befriended a wasp
that flew into his cell,

69
00:03:22,972 --> 00:03:25,630
feeding it and talking to it
like a friend.

70
00:03:26,551 --> 00:03:28,662
Some try to communicate
with fellow prisoners

71
00:03:28,686 --> 00:03:31,021
by yelling through the shower drains.

72
00:03:31,045 --> 00:03:33,410
Still though, many of these men
lost their voices

73
00:03:33,434 --> 00:03:35,797
after talking with us for just an hour.

74
00:03:36,593 --> 00:03:39,648
Their vocal cords were out of practice
speaking for that long.

75
00:03:41,188 --> 00:03:45,156
We know the impact
of long-term isolation is devastating.

76
00:03:45,180 --> 00:03:47,114
This borders on common sense.

77
00:03:47,895 --> 00:03:50,492
It's why harsh prison systems
and torture regimes

78
00:03:50,516 --> 00:03:53,672
routinely use solitary
as a form of severe punishment.

79
00:03:54,188 --> 00:03:57,656
And why none of us would tolerate
having a loved one,

80
00:03:57,680 --> 00:03:59,903
like a parent or a child,

81
00:03:59,927 --> 00:04:04,188
locked alone in a small bathroom
for days, let alone years.

82
00:04:05,069 --> 00:04:06,219
Or decades.

83
00:04:07,866 --> 00:04:10,444
In the course of representing
that first client at ADX,

84
00:04:10,468 --> 00:04:13,151
we learned about another man,
Tommy Silverstein,

85
00:04:13,175 --> 00:04:16,049
who the Federal Bureau of Prisons
put in solitary confinement

86
00:04:16,072 --> 00:04:19,687
under a "no human contact" order in 1983,

87
00:04:19,712 --> 00:04:21,831
after he killed a corrections officer.

88
00:04:22,355 --> 00:04:24,376
Tommy was 31 years old.

89
00:04:25,355 --> 00:04:26,958
Now he's 66.

90
00:04:27,363 --> 00:04:30,393
He's been in solitary
confinement for 35 years.

91
00:04:32,488 --> 00:04:35,734
Struggling to find the words
to capture his experience of ADX,

92
00:04:35,758 --> 00:04:38,885
Tommy, who has become
an accomplished artist,

93
00:04:38,909 --> 00:04:40,480
drew it instead.

94
00:04:41,800 --> 00:04:45,356
Unless we start to change
how we treat prisoners in this country,

95
00:04:45,380 --> 00:04:48,593
he'll probably be there
for the rest of his life.

96
00:04:49,736 --> 00:04:51,528
Both John McCain and Nelson Mandela

97
00:04:51,552 --> 00:04:54,466
said that of all the horrors
they suffered in prison,

98
00:04:54,490 --> 00:04:57,085
solitary confinement was the worst.

99
00:04:57,109 --> 00:04:59,149
That's because solitary
puts people at risk

100
00:04:59,173 --> 00:05:01,791
of losing their grasp on who they are,

101
00:05:01,815 --> 00:05:04,815
of how and whether
they're connected to a larger world.

102
00:05:05,523 --> 00:05:07,975
As psychologist Dr. Craig Haney explains,

103
00:05:07,999 --> 00:05:11,094
that's because human identity
is socially created.

104
00:05:11,761 --> 00:05:15,095
We understand ourselves through
our relationships with other people.

105
00:05:15,633 --> 00:05:19,918
Solitary confinement can make you change
what you think about yourself.

106
00:05:19,942 --> 00:05:22,874
It can make you doubt
whether you even have a self.

107
00:05:23,435 --> 00:05:27,094
Some people in solitary
aren't even sure they exist,

108
00:05:27,118 --> 00:05:29,824
so they'll mouth off
to a corrections officer

109
00:05:29,848 --> 00:05:32,299
and end up getting shackled or beaten.

110
00:05:32,323 --> 00:05:34,923
But at least then, they know they exist.

111
00:05:36,120 --> 00:05:41,104
Over time, some of the men in ADX
break down in obvious ways,

112
00:05:41,128 --> 00:05:43,707
like banging their heads
on the walls of their cells

113
00:05:43,731 --> 00:05:46,016
or smearing themselves with feces.

114
00:05:46,823 --> 00:05:50,090
Or attempting suicide,
some of them successfully.

115
00:05:50,514 --> 00:05:51,938
Many people cut themselves

116
00:05:51,962 --> 00:05:55,554
just to feel the pain that keeps them
tethered to the real world.

117
00:05:56,300 --> 00:05:57,972
Others adjust,

118
00:05:57,996 --> 00:06:00,887
showing no outward sign of mental illness.

119
00:06:00,911 --> 00:06:03,947
But there's grave harm
in the adjustment itself.

120
00:06:04,606 --> 00:06:07,257
That's because the experience
of long-term isolation

121
00:06:07,281 --> 00:06:10,534
can paradoxically lead
to social withdrawal.

122
00:06:10,558 --> 00:06:13,122
At first, people are starved
for human contact,

123
00:06:13,146 --> 00:06:14,331
but over time,

124
00:06:14,355 --> 00:06:16,926
it becomes disorienting, even frightening.

125
00:06:16,950 --> 00:06:18,764
They can't handle it anymore.

126
00:06:20,133 --> 00:06:22,864
All of this amounts
to a prolonged social death.

127
00:06:23,245 --> 00:06:26,721
The men in ADX are stuck
in suspended animation.

128
00:06:27,261 --> 00:06:29,047
Not really part of this world,

129
00:06:29,071 --> 00:06:32,602
they're not really part of any world
that's fully and tangibly human.

130
00:06:33,395 --> 00:06:37,283
It's for all of these reasons
that international human rights law

131
00:06:37,307 --> 00:06:40,007
prohibits the use
of long-term solitary confinement.

132
00:06:41,046 --> 00:06:44,578
In fact, the UN has called on governments
to ban the use of solitary

133
00:06:44,602 --> 00:06:46,401
for more than 15 days.

134
00:06:47,522 --> 00:06:49,164
As of today,

135
00:06:49,188 --> 00:06:53,856
Tommy Silverstein has been
in solitary for 12,815 days.

136
00:06:55,887 --> 00:06:58,650
Now in judging other countries'
human rights records,

137
00:06:58,674 --> 00:07:01,895
the US State Department has called
the use of long-term solitary

138
00:07:01,919 --> 00:07:03,561
a human rights violation.

139
00:07:04,236 --> 00:07:05,966
In 2009, for example,

140
00:07:07,395 --> 00:07:13,502
State Department condemned
Israel, Iran, Indonesia and Yemen

141
00:07:13,526 --> 00:07:15,259
for their use of solitary.

142
00:07:15,994 --> 00:07:18,794
But we allow it to happen on our own soil.

143
00:07:20,073 --> 00:07:24,193
When a prison is located in the US
instead of China,

144
00:07:24,217 --> 00:07:28,601
when it's run by the federal government
and not some rogue sheriff,

145
00:07:28,625 --> 00:07:31,855
when it has state-of-the-art technology
and gleaming floors,

146
00:07:31,879 --> 00:07:34,954
not overcrowded cells
and decrepit facilities,

147
00:07:34,978 --> 00:07:37,828
it's harder to believe
that torture happens there.

148
00:07:38,319 --> 00:07:43,065
But it's important to entertain the idea
that, sometimes, this too

149
00:07:43,089 --> 00:07:44,889
is what torture looks like.

150
00:07:45,931 --> 00:07:47,202
As a civil rights lawyer,

151
00:07:47,226 --> 00:07:50,321
I believe it's important
to ensure that people,

152
00:07:50,345 --> 00:07:52,892
even those convicted of terrible crimes,

153
00:07:52,916 --> 00:07:55,315
aren't tortured by our government.

154
00:07:55,339 --> 00:07:56,958
And if this talk were a movie,

155
00:07:56,982 --> 00:08:01,212
I'd tell you next about how we fought
and fought and eventually won.

156
00:08:02,633 --> 00:08:04,212
But this isn't a movie.

157
00:08:04,236 --> 00:08:07,712
So I'll tell you, instead,
about how deeply this injustice is hidden.

158
00:08:08,117 --> 00:08:10,387
How difficult it is to expose it,

159
00:08:10,411 --> 00:08:12,677
and why it's important that we do.

160
00:08:14,165 --> 00:08:17,960
You'd think that lawyers,
people who work in the justice system,

161
00:08:17,984 --> 00:08:20,387
would know what happens in our prisons.

162
00:08:20,736 --> 00:08:24,093
But I'm a lawyer, and I live
less than two hours away from ADX.

163
00:08:24,638 --> 00:08:26,766
And until we went
to see that first client,

164
00:08:26,790 --> 00:08:28,923
I didn't know anything about it.

165
00:08:29,265 --> 00:08:31,208
I don't think that's an accident.

166
00:08:32,225 --> 00:08:35,020
ADX walls itself off from public scrutiny.

167
00:08:35,823 --> 00:08:38,283
In the 25 years since it opened,

168
00:08:38,308 --> 00:08:41,626
it's allowed only a single visit
by human rights organizations.

169
00:08:42,269 --> 00:08:44,864
Journalists are routinely denied entry.

170
00:08:44,888 --> 00:08:46,419
Mail is censored.

171
00:08:47,214 --> 00:08:49,594
And even when rare family visits occur,

172
00:08:49,618 --> 00:08:52,055
they're monitored
by an unseen government official

173
00:08:52,079 --> 00:08:54,213
who can cut the visit off without notice

174
00:08:54,237 --> 00:08:57,055
if he thinks that the prisoner
is talking in too much detail

175
00:08:57,079 --> 00:08:58,945
about the conditions in ADX.

176
00:09:00,037 --> 00:09:03,791
In China, in Russia,
they keep out the human rights observers,

177
00:09:03,815 --> 00:09:06,215
keep out the media, keep out the UN.

178
00:09:06,712 --> 00:09:07,862
And so do we.

179
00:09:08,776 --> 00:09:11,537
ADX is, in the words of one journalist,

180
00:09:11,561 --> 00:09:13,561
"a black site on American soil."

181
00:09:14,546 --> 00:09:19,260
We know that secrecy is a hallmark
of places that torture.

182
00:09:19,998 --> 00:09:23,371
But after years of shining a light,

183
00:09:23,395 --> 00:09:26,596
we now know more about
the conditions in Guantanamo

184
00:09:26,620 --> 00:09:28,334
than we do at ADX.

185
00:09:29,343 --> 00:09:30,494
Five years ago,

186
00:09:30,518 --> 00:09:33,509
when there was a hunger strike
and force-feeding at Guantanamo,

187
00:09:33,533 --> 00:09:35,822
the same thing was happening at ADX.

188
00:09:35,846 --> 00:09:37,656
But you probably didn't hear about it

189
00:09:37,680 --> 00:09:40,306
because the government
gagged family members and lawyers

190
00:09:40,330 --> 00:09:41,782
from talking about it.

191
00:09:42,561 --> 00:09:44,188
But here's the thing:

192
00:09:44,212 --> 00:09:47,918
the American criminal justice system
is supposed to be transparent.

193
00:09:48,680 --> 00:09:50,553
And before someone gets sent to prison,

194
00:09:50,577 --> 00:09:52,466
that's largely true.

195
00:09:53,347 --> 00:09:56,164
Legislators meet in public
to debate and define the laws

196
00:09:56,188 --> 00:09:58,255
that prohibit criminal conduct.

197
00:09:58,883 --> 00:10:02,508
Citizens in our community
serve as jurors on criminal trials.

198
00:10:02,845 --> 00:10:04,631
And if you want to watch a trial,

199
00:10:04,655 --> 00:10:06,921
the courtroom doors are wide open.

200
00:10:07,774 --> 00:10:10,962
After the trial, though,
our commitment to transparency ends.

201
00:10:11,875 --> 00:10:13,954
With the prison door securely shut,

202
00:10:13,978 --> 00:10:15,804
what happens behind prison walls

203
00:10:15,828 --> 00:10:17,561
stays behind prison walls.

204
00:10:17,970 --> 00:10:20,339
And without the scrutiny
of the public gaze,

205
00:10:20,363 --> 00:10:21,763
the darkness festers.

206
00:10:23,601 --> 00:10:24,866
Other than execution,

207
00:10:24,890 --> 00:10:28,242
incarceration is the most
intrusive power of the state:

208
00:10:28,266 --> 00:10:30,733
the deprivation of citizens' liberty.

209
00:10:31,385 --> 00:10:33,028
But no government institution

210
00:10:33,052 --> 00:10:36,401
is more opaque and less
accountable than prison.

211
00:10:36,425 --> 00:10:38,811
Even though prisons
are supported by tax payers

212
00:10:38,835 --> 00:10:42,267
and return 95 percent
of their residents to our communities.

213
00:10:43,038 --> 00:10:47,577
It's that secrecy that allows
the ADX to disappear people.

214
00:10:49,038 --> 00:10:52,728
And so we have an obligation,
said Justice Kennedy,

215
00:10:52,752 --> 00:10:54,588
as a democracy and as a people,

216
00:10:54,612 --> 00:10:57,875
"we should know what happens
after the prisoner is taken away."

217
00:10:58,220 --> 00:11:02,391
The prison system is the concern
and responsibility of every citizen.

218
00:11:02,415 --> 00:11:03,955
This is your justice system.

219
00:11:03,979 --> 00:11:05,512
These are your prisons.

220
00:11:06,360 --> 00:11:08,360
Torture happens in the dark.

221
00:11:08,384 --> 00:11:13,418
And so we need to embrace the admonition
that sunlight is the best disinfectant.

222
00:11:13,442 --> 00:11:16,728
Not only because we need to know
what happens inside ADX,

223
00:11:16,752 --> 00:11:19,458
but because the knowing itself
can create change.

224
00:11:20,823 --> 00:11:24,140
There's an axiom in physics
called the uncertainty principle.

225
00:11:25,101 --> 00:11:29,053
It teaches that the mere
fact of observation

226
00:11:29,077 --> 00:11:30,910
can alter, will alter,

227
00:11:30,934 --> 00:11:33,468
the subatomic reaction being observed.

228
00:11:34,204 --> 00:11:35,514
In other words,

229
00:11:36,458 --> 00:11:38,992
watching something affects its course.

230
00:11:39,577 --> 00:11:41,783
In a democracy like the US,

231
00:11:41,807 --> 00:11:44,786
prisons are administered in our name
and on our behalf.

232
00:11:45,500 --> 00:11:48,531
The conditions in ADX
implicate our tax dollars,

233
00:11:48,555 --> 00:11:50,039
public safety

234
00:11:50,063 --> 00:11:51,253
and, most of all,

235
00:11:51,277 --> 00:11:54,587
our shared belief in the inherent dignity
of every human being.

236
00:11:55,881 --> 00:11:58,266
We have an obligation to bear witness.

237
00:11:59,079 --> 00:12:00,238
Thank you.

238
00:12:00,262 --> 00:00:00,000
(Applause)
