My dads also gotten a ticket for them being illegal. (He was actually driving my truck) but they didnt take it at least. I called the next day after I got pulled over and confinscated and they said that being it was illegal, they wouldnt give me it back. I asked why they sell them here and they basically told me that it was stupid that they sell them here, and told me again it was illegal. I have a buddy who is a cop here in town and even asked him if he could get it back for me and he told me I was poop out of luck. And also told me that radar detectors only work when the radar gun is on, so a trick they do now is if they see a potential speeder, right when in range they will turn the gun on, and by that time your already screwed. Anyway I was pretty pissed cuz I paid over $300 for my detector like 3 weeks before it got confinscated. basterds.
But yeah theres alot of stuff thats illegal but they still sell it. At least in Mn.. They blue tinted headlights are illegal here in Mn. but you can go to any auto parts store and buy a set. Also under body neon, is illegal, but yet they sell it all over. Window tint. You can go into any tinting place and get your windows tinted however ya want, But in mn. the law is 50% all the way around with the exception of the back window which can be 30%. (This is all stuff I have been nabbed for). And recently a buddy of mine had boughten a glass pipe (For tobacco of course..hehe) and on his way home he got pulled over and he had it sitting on the seat (In a clear bag) so it wouldnt get broke, and he got a perafinilia (Sp?) charge for it and it wasn't even used, and was told it was illegal to even have it in possesion. He asked why they sell it then, and even told them he smoked tobacco out of it (lol) but he still got the $90 fine and now has a parafanilia charge on his record. It was total bullshit.
