I think ConSigCor has it right. You can overwhelm papers check points, and cause them to spend resources. Making the thought of future check point a budget consideration.

Breacher, I have seen many youtube videos of Drivers License check points in Tennessee, Ohio and other states these are not Terrorist searches.. These are the types of vehicle block you do..

But of course you cannot assume every lock down like Boston's martial law one, is justified.. People have to learn to protect themselves.. I will not live in fear, or live under the boot of a police state.
