I highly recommend you watch Small Axe Mangrove a 2020 film directed by Steve McQueen and streaming on Amazon. The film is about some West Indian people living in London in the 1960s who experience persecution by the police. When the police vandalize their restaurant, the Mangrove, the community protests and a number are arrested.
The second half of the film is a courtroom drama that is very funny. I loved it. There is also a lot of good ska music in the film.
