Legal Question in Constitutional Law in Kentucky

The fact pattern here is a prime example of NOT having probable cause to search a vehicle (nor did the officer have any grounds to order you out of the vehicle), and had you been indicted, the evidence (i.e. the shotgun) should have been suppressed as "fruit of a poisonous tree" (of course, that's if you can dispute the testimony of the police officers who will testify that the K9 unit indicated drugs were in your vehicle). If you can find a local attorney interested in filing a lawsuit against the police department, you might have a case, but likely the police officers will simply state that the K9 unit indicated there were drugs inside the vehicle and it's your word against all of theirs. (Guess who wins?)

In the future: Don't be in "bad" areas of town driving, particularly if you happen to be a minority or if you happen to have any sort of criminal record (they have laptops in their squad cars that can run your plate and pull up your criminal history). Also, if your phone has a video or audio recording feature, use it when you get pulled over. It just might save you 60 days in jail next time.
