Catch & Release.

It’s not the title of a new romantic comedy, rather, it’s our dangerous policy of neither holding nor deporting dangerous illegal aliens:

Federal immigration officials allowed scores of violent criminals — some ordered deported decades ago — to walk away from Harris County Jail despite the inmates’ admission to local authorities that they were in the country illegally, a Houston Chronicle investigation found.

A review of thousands of criminal and immigration records shows that Immigration and Customs Enforcement officials didn’t file the paperwork to detain roughly 75 percent of the more than 3,500 inmates who told jailers during the booking process that they were in the U.S. illegally.

Although most of the inmates released from custody were accused of minor crimes, hundreds of convicted felons — including child molesters, rapists and drug dealers — also managed to avoid deportation after serving time in Harris County’s jails, according to the Chronicle review, which was based on documents filed over a period of eight months starting in June 2007, the earliest immigration records available.

Other key findings in the investigation include:

•In 177 cases reviewed by the Chronicle, inmates who were released from jail after admitting to being in the country illegally later were charged with additional crimes. More than half of those charges were felonies, including aggravated sexual assault of a child and capital murder.
•About 11 percent of the 3,500 inmates in the review had three or more prior convictions in Harris County. Many had repeatedly cycled through the system despite a history of violence and, in some cases, outstanding deportation orders.

The investigation found that the federal government’s system to identify and deport illegal immigrants in Harris County Jail is overwhelmed and understaffed. Gaps in the system have allowed some convicted criminals to avoid detection by immigration officials despite being previously deported. The problems are national in scope, fueled by a shortage of money and manpower.
