I can only think about what heros the air marshals would have been had they found the bag contained a bomb and their actions prevented it from being detonated.
I continue to be frustrated by the endless discussion at these situations when they start talking about why the law enforcement folks could not have done more precise shooting to disable the person rather than injure them so badly that they die as a result of these injuries.
As I understand it, there were 5 shots fired and the suspect was stopped. This is much better shooting than many law enforcement situations.
I do feel for the widow and the suspect's family.
Play hard, shoot often, leave well worn guns!
