More than one million immigrants  have been deported since Pres. Obama took office.  Under his  [Cheney-style] administration, deportations and detentions have reached record levels.   With it have come complaints of rape, torture, abuse, indefinite detention, and harsh  treatment, including charges that families have been unfairly separated  after being caught in nationwide dragnets.  The administration has  promised to make the detention system more humane or to more selectively  target serious criminals.  But it faces Republican critics  urging stricter measures -- and a growing backlash among compassionate voters and Latinos, a  key 2012 electoral force. This is a powerful journey into the secretive world of  immigrant detention, with a penetrating look at those being detained  and the abuses they are put through.- WATCH on air and online beginning Tuesday, Oct. 18, 9:00 pm ET on PBS (check local listings).

During her three months there, Mary says she endured repeated sexual assaults by a guard. Her voice choking with emotion, she told me how she tried to fight him off, and how he threatened her. “He said, ‘if you tell anyone, you wouldn’t come out of here alive to see your family.’ So then, who do you go and tell?”
(PBSNewsHour) PBS.org A year long investigation examines the current U.S. immigration enforcement system and uncovers hidden stories of abuse in detention system. Hari Sreenivasan interviews Frontline's Maria Hinjosa.
A cache of government documents recently obtained by the ACLU details  more than 170 allegations of sexual abuse during the past four years.   And FRONTLINE’s investigation uncovered more than a dozen stories of  sexual abuse at Willacy, and many other accounts of racial and physical  abuse.
When we visited Willacy, ICE would not let us talk with detainees or interview the local ICE officials. But we did speak with dozens of former detainees and staff.
In 2009, Twana Cooks-Allen was the mental health coordinator at Willacy. She was asked to survey all detainees as part of a broad review of the detention system, undertaken by ICE officials in Washington. When Cooks-Allen delivered initial findings of the survey, she says local ICE officials began a cover-up. More
