Brilliant (and hilarious) example of how to refuse an ID checkpoint:
Police State U.S.A. with Checkpoint Charlie
Steven Anderson driving westbound on I-8 in Southern California, which is an East-West highway that never intersects the international border.
"Umm, no thanks. I'd like to just go on my way..."
"Are we in Nazi Germany now, and I need to show my papers..."
"I don't have to answer you because I have rights as an American..."
Update. This is a must see.
Steven Anderson from 3 years ago, beaten and tazed by the Border Patrol.
Must see update.
