A local restaurant in my area sponsors a weekly cruise night. Last night happened to be "Camaro Night". A bunch of us locals brought our cars as it was a pretty nice evening. The lot had filled up pretty quickly and forced any other attendees to park in another lot near the restaurant. 2 friends got stuck parking in there so we took a walk over to check out their cars. After a few minutes of BS'n 2 white vans and a bunch of cars swarmed 2 pickup trucks in the next aisle from where we were standing. About a dozen guys in "ATF" flak jackets jumped out carrying pistols and assault rifles. They pulled a guy out of 1 of the pickups and threw him down on the ground. In the meantime city police blocked off every entrance to the area. Within 2 minutes it was all over and they were gone. Jaws dropped, we just stood there stupified. We were so close to this happening luckily we didn't end up in jail to.
Now I know what it's like to be in a live filming of COPS.
