#Texas governor Abbott signs law giving state police the power to arrest illegal immigrants.
Here's why this won't work ... Other than the obvious (federal jurisdiction), if local police enforce this their jails quickly will fill up. INS won't come to get them, because it's a state law.
When I was in law enforcement in the 1980s, we didn't detain suspected immigrants for this reason. No place to put them, better things to do with the jail space.

I'm still convinced we'd find quite a few from the Tang Reign of Terror were we to deploy drones.
