Wow! Funny way threads turn and twist. LOL
Cody, The guy that called you could end up in a world of hurt trying to fall back on having been an Lt. in Army way back when. A cull like that needs a pruning he'll remember. You were way nice about it and that is NOT a bad thing at all. You did good.
Being a cop myself I know that the first thing you do is fully identify yourself and your agency and your legal basis for being involved. Anything less and you own all the trouble you get yourself in.
On one occasion I had a neighbor getting mad at me about "damage" he said we had caused. I knew that his falling down shed was there before hand and had zero, zilch, nada, to do with the tree we took down. He gets all connected and authoritative sounding, implying that he held some rank in local law enforcement. Poor SOB didn't know I was sworn LEO doing tree work off duty; and I pretty well recognized all the cops around to boot.
I pushed him a little, hoping he'd just make an outright claim, but he never did. Then I told him that he was violating the law about inpersonating an officer. I told him the jail time that carried. I told him he knew the shed was already damaged and he would not scam me or my company. I had that guy crawling and saying how sorry he was in a few short minutes. Never did tell him I was cop; I always like to hold a little something in reserve.
Mr. HE
