re: Acceptable to call the police to report "panhandlers" at a neighborhood market place?

If you do, wait until right before you go back next time. Because if you call them now and they actually do something, it will give them enough time to get right back to where they are the next time you go there.

Just ignore the frick out of them. That's what I do. I don't even give them the time of day.

You can't call the police every time there is something that makes you feel uncomfortable, but seriously. Once you start to ignore the frick out of them you will get used to it and it will eventually not even bother you anymore.
