No unarmed citizen at this point has tried to approach the killer after he fired his single shot.Neither has an armed policeman who was present.
Civilians aren't soldiers either, and can't be expected to exhibit the heroism of charging in the direction they perceive the shot to come from in order to catch the perp. Even if they are armed. They haven't done this yet, and I doubt they will.
BTW, are you speculating from the standpoint of having been shot at or just speculating? It doesn't reflect on you either way (very few people have been shot at), I'm just curious.
The only policeman that was present never heard the shot. He was completely unaware that something had happened. This was the officer at the gas station. If you know of any officer who heard the shot and saw a victim fall, let me know which incident it was.
You're asumming that all of the witnesses somehow have to be downrange of this killer. There have been numerous people who have been in the area and to them the shot was loud. I don't expect anyone to try to investigate a shot and be unarmed.
I have had numerous loaded guns pointed at me. I also have had shots fired passed me and near me. I have a very good perception where a shot comes from, how far away and the approximate caliber.
I do not expect someone to go charging up to a killer like he was going up San Juan Hill.
