I think its all about probable cause. Just because they are aware of drug traffickers doesnt mean he is one. They have to have some kind of reason to pull you over to search i.e. thick smoke coming out of your window because your smokin too much of that shit. Its like the exhaust thing. I got pulled over one time because I had a loud ass fart can on my car when I got it, and the cop told me that the only reason why he pulled me over was because it was so loud. He knew it was modified and therefore had probable cause to pull me over. I told him I got the car that way and I was workin on getting rid of it cuz that shit was annoying and he let me go. As far as other mods are concerned I donno how or why they could find cause to pull you over. Just ask them why and and why some more. They have to have a legitimate reason to pull you over. If they dont have one, you shouldnt have to show them shit. You have rights and they are just another person doing their job. Some pigs just take advantage of their power with their guns and badges and think they are tough shit and they can get away with anything.. it sucks
