You are right that a crowded situation is a tough place to call for everyone to begin firing to stop a crime... I think the point that is valid is that fewer perps would ~try~ to go into a public place shooting if they thought everyone in the room might be armed. It is the psychology of 'gun free zones'.

I agree, although I don't think that would have made a difference with this particular crime.
