I remember this story well.

DeBlasio/Shea defended NYPD's actions by claiming they were arresting looters and rioters who violated the city curfew.

But it turned out NYPD kettled in a large group of protestors before the 8 PM curfew, didn't let them leave, and then claimed they were violating curfew after it was 8 PM.

I am all for cracking down on opportunistic rioters and looters, but NYPD was more interested in the low-hanging fruit of peaceful protestors.
