Mississippi

This was a few years back. Traveling to Mississippi, (flying in to Alabama the driving to Mississippi). The atmosphere in Mississippi seemed as though we traveled back in time. Everything was kool until we were leaving to drive back to Alabama. We get on the highway in our rental car, about 30 minutes into our drive, we begin getting tailed by a cop. He goes to one side then to the other to see who was in the vehicle. My fiance at the time was driving. Her, fair skin Puerto Rican and me brown skin black man. This goes on for about 15 minutes. Until we pull off to get breakfast.. About 30 minutes later we get back on the road. Same cop literally waited in between 2 parked trailers and proceeds to follow us again. He finally stops us and says we were going 58 in a 45..signs clear as day say 55.luckily a black cop pulled up behind us and for a second he stuck to his story until the black cop advised him to drop it
