Flora and George are both right. IMHO, one of the reasons that guns are more lethal than knives in such situations is that they’re not as directed. What I mean is that, if I’m trying to stab you, the chances are that I won’t accidentally stab the the guy sitting next to you (and if I’m that clumsy, I probably won’t do any harm anyway). But with guns, especially automatic weapons, you can injure or kill an awful lot of people without being real specific about it. So I can hurt or kill a lot of people when I try to shoot you.
Just for the record, this is a non-specific “you”; I wouldn’t dream of harming anyone on this message board.
