Ways to prevent front windows tint checking?

For example, the police pulls you over for lets say speeding. You put down your window half way and he sees the tint on the other half. He then gives you a ticket for the tint.
Now this time, you get pulled over for speeding again. What if you put down BOTH of the front windows before he walks to your car? Does he have the authority to make you put your windows up to check if it is tinted or not? Can you simply say,"No I will not put up my windows"?

Just curious on this one.
