Before Chicago's pistol ban was struck down, there would occasionally be a case of self-defense. Most recently was a year or two ago, when a pair of rats were throwing bricks at an elderly woman through her window. She shot one with an "illegal" pistol.
Turns out one of the punks, though a hardened thug already, was 14. He didn't die, but we got to hear the usual activist reporters moan about the "child" that was shot, what a "nice boy" he was, honor roll student at CPS in between arrests and bouts of truancy, etc.
Despite their bleating, the actual victim wasn't charged with anything, though I'm assuming her pistol was confiscated. Since the ban was struck down, they rammed through an equally unconstitutional registration program that no one is using. You can expect self defense episodes where the aggressors belong to a pet group to result in the media giving the mamas and rev'rens all the camera time they want to pretend the thugs were the victims, but even our nutjob prosecutors aren't likely to go to trial.
The city is an absolute disaster, but I think whatever law abiding citizens are left are starting to wake up.
