The 'Dragged Across Concrete' which is based on a true story probably focuses on the dark and gritty aspects of urban life. It could be about the power dynamics between the police and the criminals they pursue. Maybe it shows how people get dragged into dangerous situations against their will, much like the title implies, in a world full of crime and corruption.
I'm not entirely sure who the specific main characters are based on in real life. But in the movie, there are likely characters representing the police officers who are involved in the complex situations, and also the criminals they are dealing with.
In a way, it has roots in real-life situations. However, like many movies, it might have taken some artistic liberties to make the story more engaging and cinematic.
Concrete Cowboys is not a true story. It's likely inspired by various elements but doesn't represent real events or people. The plot and characters are crafted to engage the audience within a fictional framework.
