The policeman then used his car to cut off the path that Radio was trying to take to continue on his way. The officer jumped out, forced Radio against his car and handcuffed him. He used the fact that Radio was colored and off, and assumed he must be up to no good. However, he definitely didn't have a correct judgment on the situation, as the agent ended up filling out piles of paperwork while Radio ate lunch with the other agents. As the film progressed, the levels of discrimination against radio decreased. As said before, the beginning of the film was full of discrimination. People just didn't know who he was. But once they realized that Radio was a very kind and genuine person, people stopped discriminating against Radio.
