In the infamous Boston Marathon bombing clip where the elderyly gentleman is knocked down by the blast, if you look at the bottom left of the screen in that video, you will see a uniformed Police Officer who is facing the finish line. Upon the first blast occurring, he turns back and heads toward the first blast. As soon as the second blast occurs, he turns and runs away from the blast sites, while others continue to run towards the first blast site, which would be the, correct, right thing to do, as it regards to scene safety (2 blasts close together -- get the hell out). So what would you have done in that situation; Go towards the injured/dismembered who are bleeding to death, or seek safety until all is clear ?
