I'll be surprised if the court actually demands that you pay for both tickets; just pay the initial ticket and the second ticket will be deleted. Otherwise, if they refuse to delete the second ticket, just go to court and ask the judge to dismiss the second ticket after proving that you successfully complied with the first ticket and paid that fine, and removed the too-dark tint.
Now, for the tint. It's wrong for you to have it.
The police officer's right to LIVE outweighs your desire for privacy, coolness, whatever. The officer NEEDS to be able to SEE you and SEE your HANDS as he approaches your vehicle. The officer's life depends on it.
Just last week an officer in Michigan was shot dead while performing a traffic stop. It is dangerous work. Imagine if your spouse were a patrol officer. Every day you'd wonder whether she'd come home at the end of her shift.
Let's show them some consideration and respect. Let's make this small concession for them, shall we? We need to give them a break here, don't you think?
Imagine a world without them, if you can. Imagine what that world would be like with no one to enforce the law, and with the bad guys free to do what they like. Sit with that for a while…
We need them … and they need to be able to SEE our hands, because the hands can kill.
