I am of the opinion that this whole thing is overblown.
Neighbor does not like the noise, so she goes over and asks them to quit down - normal.
Neighbor gets asked to leave. Neighbor leaves - normal
Some people get their feelings hurt - normal
No punches were thrown, not gun shots, not injuries or arrests. Back to the old saying “No blood, no foul”.
Lakers announcer, the late Chick Hearn would say, “No harm, no foul, no blood, no ambulance.”
Yeah, for Chicago, any interpersonal interaction that doesn’t result in 3 shot dead is Emily Post-style manners.
