kermit - let me give you another thing to think on. You wondered if they could have set up some sort of for lack of a better word "moving roadblack" and closed the road to additional traffic ect.
Well one area I know your not focusing on is the behind the scenes of law enforcement. I am very glad I dont have to be out in a car doing the actual "dirty work" - buit I dispatch so I can add a bit of light to this situation. One of the first things that you hacve to take into account is that mabey not all the agencies had the same radio systems. Here in my city we have 2 different radio systems between the local PD and the college pd that also do some helping around town. Sometimes different agencies dont have the equipment to even talk to each other - they would have to roll down their windows and yell. Just one of the intricacies of law enforcement that isnt readily known
