As usual, JohnnyT comes up with logic!
What I find interesting in the thread is the number of current/ex LEOs that offer their opinion about this tragedy. Most of them, myself included, have been in similar situations during their careers. Each situation is unique as each road is different. Furthermore, circumstances continually change as conditions improve or get worse. An accident scene is usually very chaotic. The first responder must make a split second decision as to where to position his vehicle based on his observations upon arrival. If there are injuries often he/she is set upon immediately by panic stricken witnesses/bystanders/injured parties. This further adds to the confusion. Couple this with the rubber neckers slowing to observe and the clowns trying to take a video with their camera phone and you've got to potential for more chaos.
Several LEOs have offered their opinions in this thread. It would be wise to go back and review their responses and learn from what they've posted..we seem to want to fall behind what's "legal" and forget what is simply common sense...slow down a bit and pay attention to job of driving....just sayin....Dennis
