If someone is deranged enough to want to cause harm or death to other people they will do it with or without guns. The Boston Marathon bombing is case in point. By not allowing law abiding, responsible Americans to carry guns in public areas like schools, shopping malls, etc, all we are doing is inviting someone disturbed to target that place. They know that any responsible person won't be armed there and they can do as they please. Would you put a sign in your front yard that says "We don't have any guns here!" That's like telling criminals "Come on in, we're defenseless." Law Enforcement does the best that they can but they can't be everywhere all the time. I would feel much safer knowing that there may be someone close that is responsible and armed close by to take down some lunatic if the need arises. The criminals are armed, why can't we responsible Americans be allowed to and protect the innocent?
