From this:

The Department of Homeland Security is systematically reviewing thousands of pending immigration cases and moving to dismiss those filed against suspected illegal immigrants who have no serious criminal records, according to several sources familiar with the efforts.

Culling the immigration court system dockets of noncriminals started in earnest in Houston about a month ago and has stunned local immigration attorneys, who have reported coming to court anticipating clients' deportations only to learn that the government was dismissing their cases.

Richard Rocha, an Immigration and Customs Enforcement spokesman, said Tuesday that the review is part of the agency's broader, nationwide strategy to prioritize the deportations of illegal immigrants who pose a threat to national security and public safety. Rocha declined to provide further details.

Critics assailed the plan as another sign that the Obama administration is trying to create a kind of backdoor "amnesty" program.

This might be a test program that they'll be rolling out nationwide. Nine months ago I urged people to ask Janet Napolitano about the DHS refusing to deport those who were involved in immigration enforcement actions ("silent raids"). If you want to stop this apparent test program in its tracks, help promote plans like that. If you don't, all the wailing and gnashing of teeth isn't going to be effective: the Obama administration is just going to do whatever they want to do. Challenging them to their face on video with tough questions would definitely put a crimp in their plans.
