That's a 'given' - a 'fact of life' - even where guns are supposedly 'outlawed.' The only real question for society is, 'Who do you WANT to have a gun?' The law-abiding neighbor, or teacher, or student, who can help you when you need help? Or only (by definition, where guns are banned) the criminals?
Only RESPONSIBLE and well trained people should have access to weapons in those type of situations. I see no problem with well certified citizens carrying weapons in public, but I don’t think every hot headed 18 year old on campus should be packing heat as some posters have advocated.
