According to current Florida law you can get a gun, follow an unarmed minor, call the police, have them explicitly tell you to stop following [the minor] and choose to ignore that, keep following the minor, get into a confrontation with them, and if at any point during that process you get scared you can shoot the minor to death, and the state of Florida will say, 'Well, look: you did what you could.'
