Yeah, I couldn't believe it either.
He actually pulled me over for my system being to loud, and I even had my windows down
And then he said "Lets check your windows"
It read 15% all the way around, but I got them tinted at 18%....who knows
So he said I got lucky because he through the sound violation ticket out ($165.00), and just decided to slap me with a 15-day window correction....Blahhhh
