I dont know the circumstanses of his encounter with the "cop". I know they patroll here, and maybe even sneak around, but dont let this guy intimidate you. Is he in a marked car? in uniform with a badge. Polst his name and badge # here. If hes undercover, it could be an impersonator. dont call non emergency, call 911. its that important to stop him, plus then there will be a record of the call
