Caller ID says "Bucks Co FOP" and he said he was Ken Johnson of the Bucks County Police Chief Association but he hung up when I asked if he was soliciting.

Also calls from:
215-343-6185 "Bucks Co Pol"
215-343-1719 "Bucks Co Pol"

There is no answer when I call any of these three numbers during regular business hours and I would expect genuine police to answer their phone.
