"Since 1992, the police department has barred officers from asking people who aren't under arrest about their immigration status. The order also prohibits them from arresting people solely based on suspicion that they are in the country illegally. Police do check the immigration status of those arrested on Class B misdemeanor or more serious charges."
And I thought they were smarter than that in Houston.
They do the same thing here in Liberal Loonyland, AKA New York City. The "powers that be" practice, "Don't ask, don't tell" when it comes to illegals. We have had an open door policy in NYC towards illegal invaders for decades. We are constantly reaping the rewards of this lunacy in terms of violent crime. Wake up, America.
