I know a cop in NYC, unless she's retired by now, who would love you.
She was as anti-tint as they come, because she once got shot at by a guy in a back seat, behind tint, that she didn't see. After that she went on a tint vendetta.
And you did
not want to argue with her over getting the ticket. My brother (NYPD Auto Crimes detective, retired now) told me about one stop she made that went like this...
"The tint on your windows is illegal. You're getting a summons for it."
"Aw, give me a break, everybody has tint!"
"Now you're getting a separate summons for
each window that's tinted."
"What? You can't do that! I'll have your badge!"
"Well, if you could prove that it was a legal level of tint..."
"Yeah, yeah! It's legal, I swear!"
"But I don't see the required stickers showing the tint level. So we'll have to test it."
"Okay, go ahead and test it."
"Alright sir, give me the keys."
"The keys? What do you need the keys for?"
"Well, to test it I have to impound it. The police lab will test it and we'll go from there. Shouldn't take more than six to eight months for them to get to it."
"What? You can't take my car for six to eight months! How will I get to work?"
"Well, if you want to claim it's legal tint so I won't write the summonses, it will have to be tested."
(I should note here that the fine was $250... each summons. 6 Windows, $1,500 in fines the guy was looking at.)
"You don't have any other way to test it?"
"No... well, maybe... Would you object if I took a small sample of the tint from each window for testing?"
"How big a sample?"
"Oh, not big. Less than half an inch."
"Oh, sure, go right ahead!"
Officer takes out her baton and smashes out the back window, reaches in and picks up a few pebbles of the broken glass... "That's one sample..."
The guy was then more than happy to get the 6 tickets.
I have no idea if this is true or not, or if it was embellished in the telling, but my brother told it to me and I heard it from other detectives in his squad at other times.
