First of all, wow my phone tried to autocorrect “gun” to “fun”.
Secondly, my state has a “stand your ground” law, but requires that you not “use excessive force” unless you can prove your life was in danger.
I saw a video tonight of a mob approaching/surrounding a guy with a gun, and they didn’t touch him, though at any moment they could’ve jumped him and beaten/killed him. Would responding with lethal force be justified in that situation?
I am not a lawyer and many of these things very from state to state. Generally speaking, however, your life does not have to be in danger. You have to have a reasonable fear that your life is in danger. If someone is aggressively charging you and shouting "I'm gonna kick your ass" that may be enough. Check with a lawyer in your local state, however, for specifics.
