Say adios to your 4th amendment rights.

Tough call that. I mean, if you're caught doing something illegal even accidentally... aren't you still doing something illegal? So, a cop stops you for not wearing your seat belt but when he gets to your car door he sees that your seat belt was just twisted in an angle that made it hard to see from a distance, he apologizes and turns to walk away when he notices a piece of torn clothing sticking out of your trunk and asks you to open it and he finds a murdered body. Even though his reason for stopping you proved to be a mistake you are still a busted ass murderer right?

In the real case if the officer was unaware of a statute or inclined to arrest the guy as a "teach him a lesson" strategy (which is surprisingly common) then I guess I can't argue with the court's decision. I wouldn't approve of them using this ruling as an excuse to randomly kick in doors and search homes though.
