It all makes sense now

It has to do with history. Now I know why this movie was very Puerto Rican-like when it came to how Tre reacted.

Spike Lee's names is in the thank list on the credits in the end. Southern blacks, especially the ones form the Deep South, have a very different history. American slaveowners tended to be more humane than British owners, in that they bought whole families instead of separating them. The house servants were raised in English homes (since the masters were all Norman) - -and learned words like "bro" and "sis" from them. The black slaves who stood in the South and the ones who intermingled with the former house servants (who were not slaves by the way, cause slavery was a class system), learned the words from them and formed the Southern blacks we know today. Lee is descended from those people. It reflects in his movies. His movies focus on Hispanics instead of just being about black people. Southern black people usually don't let people to get to them like that, much like us Meditteraneans. They also say "bro" like us, but that's the English that did that lol (I supposed slavery at least had one good thing about it).

Singleton was clearly influenced by Spike, which is why this was not a typical black movie. Had Lee's influence been absent in this movie, the reaction of Tre to the cop would not have been pleasant the way it was. It would have been more like Buggin Out in "Do the Right Thing" or the self-titled character for which "Fresh" is named for -- he just outright is disrespectful to the white cop who smears him with racial slurs.

Funny thing even in "Jungle Fever" -- the black characters never confront the white ones.
