When I voted in my small town, there were two cops standing there. No fraud. No trouble. Very simple. Nothing for the cops to do. But they were there.
I would think that cops in PA (and every where else) would be present at each polling place, with a check list of behavior that are allowed and not allowed.
Biden mask? Arrest her.
Not letting a poll watcher watch the polls? Arrest her.
etc.
That’s exactly the behavior that got the GOP the 40 year consent decree. Unfortunately it isn’t going to happen.
