I actually think this is a very important topic to cover. Someone we all know has window tint. This kind of abuse of power is intolerable. I for one, am outraged.
You tell the cop you're calling your brother who's a lawyer and you wonder why he's being a prick to you? That's an asshole move and is only going to piss a cop off.
And what are these "lies" the cop supposedly told you? That sounds like your only potential argument against the cop, but you haven't given any details
