You should join the NRA if you want proof.
Along with your membership you will receive a monthly publication, The American Hunter and they cite 10 -12 actual stories of armed American citizens defending life and property, their own and others.
It happens hundreds of times a day in free states where citizens aren't afraid to stop freaks from public defecation, public stealing and other acts of insanity.
BTW, did you read about a young kid named Kyle Rittenhouse?
Yeah, the asshole rogue DA brought charges, but in the end, justice was served.
In kalifornikator, he'd still be in prison, awaiting a trial date.
This is not me puffing my chest, join the NRA and read about real American heroes.
Yeah, I didn’t think so.
Rittenhouse does not come close to your scenario, but nice try.
