Two Texans with expertise question the thinking behind an ACLU request for a federal investigation.  That group wants to know if travelers are having their constitutional rights violated by illegal searches at border crossings or check points.  Curtis Collier with U.S. Border Watch doesn't think so.

“There's a struggle down there between what is constitutional and what is not,” Collier says. “ The ACLU is probably over-stepping here.”

Now, every car or truck gets stopped.  Border Commerce and Security Council President Nelson Balido says security at crossing and checkpoints is tighter.

“The reason they're there is because it's the absolute last line of defense,” Balido says, “for drugs and folks that may want to cause harm to the United States.”

There are twice as many agents on duty, checking those vehicles now.

“It has tightened up,” Balido says.  “There's an absolute war on drugs, and then with the violence going on, especially on the Mexican side of the border, and the drug smuggling that's happening -- well, they've tightened up.”
