Well i'm not trying to be a dick here but it all seems common sense. Like i said, in your state it is PC for a traffic stop if it "appears" that the belt is not on, seeing that your window was open and therefore a clear view inside i'm sure to him it didnt look like it, the leaned back seat probably didnt help.
As far as your comment on 35% and "see thru glass", if your interior is black that makes any tint even stock windows look darker, they come with a factory tint and anything added to that is going to give an appereance far from "see thru". Now...i think you caught yourself in a lie. You said originally that the cop was hassling you about tint and you told him you dont have any tint...YOU DO HAVE TINT. So i guess your saying you lied to him? Anyways as i said before all the issues you brought up you were totally in violation of except for the belt that you said you were wearing.
I think alot of people need to realize that ALOT of times a petty traffic stop over a seatbelt or a missing front tag can lead to something much much more and thats why they do what they do. Lets say he stops you for the missing front plate....runs your license and you have a warrant or suspended license, or you have drugs or a weapon in the car or your intoxicated. The little things lead to bigger things way more often than you'd imagine. Whether you believe it or not the situation you decribed you were definately not being harrased but being checked out by a thorough cop.
One more final thing, i looked back and this was your second post here after you joined:
"I GOT 20% for the back and 35% in front
Cops don't like tints around here I get b/s for it all the time but
the car looks WAY better with all windows done.
So you know your tint is whats going to get you attention, not because you drive a LS. Are you feeling me on that?
