Jackie Mahendra points out an Associated Press story describing some of the most recent information about how we're detaining illegal immigrants -- and it's profoundly disturbing:

The U.S. detention system for immigrants has mushroomed in the past decade, creating a costly building boom in an effort to sweep up criminals and ensure that illegal immigrants are quickly deported.

However, an Associated Press computer analysis of the entire detention population on a Sunday night in January found that most did not have a criminal record and many were not about to leave the country soon — voluntarily or through deportation.

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

Of those, 18,690 immigrants did not have a criminal conviction, including for illegal entry or low-level crimes such as 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.

Almost 10,000 had been in custody longer than 31 days, the average detention stay.
