There is a freak shooting innocent people. Can you imagine for one minute being a cop who has to approach a vehicle in a roadblock who may be this sniper?

These roadblocks are probably the safest place to be. The likelihood of this sniper being in a roadblock, AND being provoked into action (as opposed to waved through) approaches zero.

Well, I think the goal here is to get the roadblock up at the right place and right time one of these times. It isn't an easy business.
