I doubt it.
Cowards prefer soft (disarmed) targets.
While I mostly agree with this sentiment, I think too, that you do an injustice when such things are discounted. Look at the Fort Hood shooter. He opened up on an army post. Granted, he probably knew that there would be no guns near his victims, yet he also didn't know how close the security detail was and who would respond to his attack or how fast they would be. Remember that the muzzies have been slaughtering both infidels and their armies since the 600's AD. The Crusades, all seven of them, didn't turn out too well for the Crusaders. Even though much of that can be tacked onto the Crusaders themselves, the mooselimb armies cannot be discounted.
