More on our own concentration camps

Private prisons run for profit and taking all comers. Locking up innocents with no access to lawyers or hearings. What country does this sound like?:

America's detention system for immigrants has mushroomed in the last decade, a costly building boom that was supposed to sweep up criminals and ensure that undocumented immigrants were quickly shown the door.

Instead, an Associated Press computer analysis of every person being held on a recent Sunday night shows that most did not have a criminal record and many were not about to leave the country _ voluntarily or via deportation.

An official Immigration and Customs Enforcement database, obtained under the Freedom of Information Act, showed a U.S. detainee population of exactly 32,000 on the evening of Jan. 25.

The data show that 18,690 immigrants had no criminal conviction, not even for illegal entry or low-level crimes like trespassing. More than 400 of those with no criminal record had been incarcerated for at least a year. A dozen had been held for three years or more; one man from China had been locked up for more than five years.

Nearly 10,000 had been in custody longer than 31 days _ the average detention stay that ICE cites as evidence of its effective detention management.

Especially tough bail conditions are exacerbated by disregard or bending of the rules regarding how long immigrants can be detained.

Based on a 2001 ruling by the U.S. Supreme Court, ICE has about six months to deport or release immigrants after their case is decided. But immigration lawyers say that deadline is routinely missed. In the system snapshot provided to the AP, 950 people were in that category.
