Gov. Rick Perry followed through on his threat to do something about border security, activating up to 1,000 National Guard troops. He said the Guard, which has strict limitations on what it can do in a law enforcement capacity, would serve as a "force multiplier" to state troopers already at the border as part of a surge operation. The federal government has plans to review Perry's action.
