Traffic Stop - WMD in a Kia?

This is an interesting video, taped by the occupants of a vehicle pulled over for speeding (72 in a 70 mph zone).  They refuse to answer the trooper's questions, and one of the men engages the trooper in a conversation about where our country is heading with unlawful stops, searches, and checkpoints.
