1) if you told the tint place to do it at 20%.....then don't expect them to change the tint for free. that would be ridiculous...and if they do, they're ridiculous.
2) if you told them "do it legal"....then they better damn pay.
3) i got pulled over in MA, a 250 dollar ticket straightened my arse out and got it redone at 40% sheets all around. (luckily, I appealed it and they let it go).
4) you could get your eye doctor to write a waver saying you're photo-sensitive and need DARK tint.....in that case I believe you go to your registry or something (i don't know the details in your state)
5) if the cop pulled you over already, you better not think he'll "forget" you cause you have your windows down.....once the weather gets cold and your driving around your parking lot with the windows down, he'll pull you over again and hand over the ticket.
6) Just get it done legally....ESPECIALLY since the cop now knows you.
just my $.02.
