Yesterday, an airline passenger was shot and killed by an air marshal. The dead man shouldn't have gone on an airplane without his medication, but he doesn't deserve the death penalty for this oversight.
The blogosphere has been too quick to forgive the air marshal without really knowing the facts. Statements like "Now we know that the air marshal system worked, and the terrorists have to consider it." (Counterterrorism Blog)
Anyone smart enough to obtain a bomb and sneak it aboard a plane is smart enough not to run around the plane yelling "I have a bomb!" Compared to all the other crowded places in which I regularly find myself, such as subway stations, the Staten Island Ferry and movie theaters, an airplane is the least likely place in which someone would actually be carrying a bomb.
The air marshal shouldn't have shot a guy in this situation with a woman screaming that it's her husband and he didn't take his medication.
