A pretty sensible summary of our current situation and the research. In my view the article GREATLY underappreciates the double whammy created by covid 19 beginning in Martch 2020. In Chicago at least, this very very quickly led to a big decline in discretionary enforcement activity, routine patrolling, responses to (usually false) alarms, issuing minor traffic citations, and the like. The coppers did a better jog at sustaining gun seizures and other important matters, but the covid whammy was a hard blow. You will recall that the rest of us also were trying to stay 10 feet from everybody and we locked our doors when we were exposed or even just got the sniffles - that was real life in the Terrible Twenties.
