I must say that over the last few years I have apparently gotten pulled over for no other reason besides my window tint.  While it is annoying, I have nothing to hide and do not really mind.  It just gives the cops a reason to stop a suspicious looking car or truck.  The key is to avoid getting fined, be sure to mention you are unaware of the tint laws.  Many times cops cannot see in these cars and feel threatened. Make sure you turn on your inside lights and fully cooperate with the officer.  Many times, they may just let you go with a warning.

It is very easy to see why cops are leery of cars with tint on them.  People can hide guns, weapons, among other things without any one being able to see them.  While the look of a car with the windows dark looks awesome, you must consider some of the consequences of doing so.

They use window tint tools that they keep in order to determine if you are compliant with the applicable laws on tints in your area. Each state is different so be sure to check your local ordinances to be certain of your rights and know the laws before they bite you in the back.

If it is thought your tints are too dark, they will bring out the window tint meter and test it to see what it rates at. Normally, anything under 50% will cause a fine, but they might let you off with a warning. Note that 0% is the darkest and anything over 50% does not even look tinted in my opinion. Some people go with 35% and it does not look too dark and most cops do not really mind. You can get your own meter and test it yourself if you want, but most just take a chance and drive around with their tints and hope for the best.
