Here in my country ( Brasil ) it’s far better to decide in such situation. Here, we do not have the right to be a jerk with a gun. So, if you see someone with a gun on streets, it’ll be probably a Cop or a Bandit, and in both cases, if you are close enough of this person, you’ll get shot. That is because neither bandits nor the cops give a shit about you. Even if you are a good citizen. And to make thing far much better here, if you have a gun, and a bandit try to hurt you or your family, and you shot him, it’s better to you to hide your ass because you’ll be hunted by the cops for shot some one and even by the bandits, for revenge, just because you try to defend yourself.
