In Chicago the curfew didn't start until 9pm. The impression I had during that first week was the curfew was to get most of the law-abiding citizens off the street ("essential workers" were excluded), so the police had less uncertainty to deal with - they were just completely overwhelmed by the amount of rioters and looters.

Rather agreed here; if anything that week has me leaning towards needing more police, not defunding them.
Quick edit: It seems they're also now on 12-hour days with no time off, apparently expecting more chaos in the coming days.
