Police departments expect protests to happen on a single day, or at most, over a weekend - they call in extra officers from nearby cities or counties, they put people on extra-long shifts, and they let the paperwork slide for a couple of days.
They don’t have officers to keep that up for a week, much less for a month. Judges will let it slide if they wait an extra day or two for arraignment hearings, but civil rights lawyers will have a good case to throw out everything if they delay much longer than that.
If arrested: DO NOT waive your right to a speedy trial. If you can at all afford the wait, DO NOT agree to plea bargain. More than 90% of cases are plea bargained out. Fewer than 5% of cases go to trial. (The difference: If they can’t get a plea, sometimes they drop the case. They may know they don’t have evidence that will hold up in court.)
Courts do not have the capacity to put hundreds of protesters on trial in the space of a few weeks. (Especially now. Courts are operating at limited capacity.)
Keep pushing. The cities that want peace are starting to make offers. The mayors and city councils who want to be re-elected, are starting to realize that this isn’t going to vanish with next week’s news cycle.
And in about another week, we’ll see the waves of COVID hit the police departments. (It’ll hit the protesters, too, and harder. But you don’t need two years of training and a hiring interview to join the protesters; police numbers are limited to what’s on hand today.)
They have limited resources. And they’re stretched thin already.
