I pressed post too soon by accident.
There is a Jewish group for Jewish neighborhood being harassed by others, and I meant to look at that further, but there's so much you could do when you're searching something else and want to go to bed an hour ago. What little I saw did not indicate anything on this level.
There was a neighborhood patrol when I was a kid around here, we called them paper tigers and either played Hide 'n Go Seek when we saw the passing through trying to scare us while we were drinking our beers, or just pointed and laughed at them. Although not always, because some of them were the fathers of people of friends.
Regardless, they were just dressed like they normally did, driving around in a Dodge Dart, no similarity to the police whatsoever. Although they had a decal with their insignia on the side of the door or something like that, was quite a while ago.
