OK, here's a refresher wrt the original post:
What got me thinking about this hypothetical situation (bar/club fight) is the gang/group voilence that our youth and senior citizens is facing today. I can remember being jumped some days when I was walking home from the school bus... I was a nerd lol. Or for a more recent and more serious example, a young gifted man in Chicago trying to escape a gang fight then being beat senseless with a railroad tie he died that day or a couple years back there was a high school girl that was gang raped at Prom. Or say you stumble upon a home invasion in progress against a elderly couple.
So the post started out as an allusion to a bar fight and progressed to gang violence, death, and rape.
