It’s not that they really wanted to violate the curfew, they were all waiting for the weepy-eyed pansy mayor to bring them masks.
Instead of the police and NG “holding ground” why don’t they send in helicopters to saturate the rioters with teargas or pepper spray and then advance on them and sweep up as much of the trash as possible. That, and arrest or shoot the instigators and their paymasters (Soros and others).
I believe the NG and LEO withdrew to safer locations.
If he and his crew aren't prime candidates for some drone work, I don't know what is.
