This video depicts the proper way to defend the Fourth Amendment at a DUI checkpoint.

For those who would find it objectionable that this driver exercised his constitutional rights in this case, your part of the problem not the cure. thus is one of the many steps the Gov took to get us to warrant-less wire taps, sneak and peaks in your home and ect ect. I have no problem with anyone giving up their rights, I am just offended when they elect officials who try to strip mine.
