I have seldom seen anyone caught at those illegal immigration checkpoints. I'll guarantee you one thing though, if they weren't there every other car would have fifteen people in them.
"I'll guarantee you one thing though, if they weren't there every other car would have fifteen people in them." Why can't catch them at the actual borders? Conversely, if these are effective messures why don't we have checkpoints in Denver, Chicago, New York, Houston, Atlanta???
