Yo lloyd banks, I know several cops that bitch about window tint but usually let it go. HOWEVER, they flip shiz if the windshield is tinted. In PA, tinting front windows is illegal, but I know several cops that overlook it. Those are the same cops that tell me that if they see a windshield is tinted they will try to fuk you as hard they can. Not sure of the laws in Baltimore, but I know in PA side window tint is frowned upon and windshield tint is a death sentence...check out your state laws and just be careful
Edit...just because some cars come with it from the factory doesn't necessarily make it legal in your state to put it on aftermarket.
