After a summer of extreme violence, homicides in Chicago were supposed to slow down going into the fall and winter months. But, that certainly does not appear to be happening as the city just recording its most violent weekend of the entire year with 52 people shot and 17 of them killed. This weekend’s violence brings the tally of year to date killings in Chicago to 646, an annual run-rate which implies the most violent year since the mid-90s.
