Source? Seems cool but I’d like to learn more

Dude was getting curb stomped and head smashed in by a blunt object before the shooting…  So my question is simple…  If a gang of masked men, who outnumber you 7:1, and are literally smashing your head in with “non-lethal” crowd management devices and causing life altering injuries while you are pinned down under thread of death, why wouldn’t self defence be justified?  I’m not saying the gun was his, or that he had control of it, or that he even fired it, but I am saying if ICE is doing this to people why shouldn’t they defend themselves.  Black Panthers just got some recruiting.  Arm yourselves and openly carry. It’s your right so use it.
