Wasn't the cop just doing his job at the end? i didn't feel like he was racist

They was evading the cops, there was an unconscious girl in there, and the cops had no idea what was going on, cause the sister earlier called the cops and acted like her sister was kidnapped or being killed. So yeah at first they pulled a gun and got everyone subdued. However once they knew what was going on they let him up and let him go saying next time just call the professionals to help.

Yet they play it like Kunle was traumatized by a terrible racist cop and he forever hates and is afraid of the police now. And i'm thinking how was the cop racist and how was Sean right? Sean acted like the police was gonna bust in and shoot everyone that was black if they came, and Kunle tells Sean at the end "You were right man" how was he right? did you get shot? you got a gun pointed at you cause you all was trying to outrun the cops acting in guilty of something and the cops was under the impression a girl was being kidnapped.
