These A & B is a cheap rhetorical trick, called the false dichotomy, because there's also C which is "you understand that guns save many more people from criminals". On the one side there are 5 thousand of innocents shot every year. On the other side there are 500 thousand of would-be killed and would-be raped innocents who used guns to defend themselves. By banning guns you're playing a demi-god who is deciding which of the two groups of innocents are less worthy, a demi-god who doesn't even care to consider all the facts and instead submits to emotions.
