i thought up a movie kinda like that, where a hitman on the west coast travels to the south and east to kill gang members, and his job is easy because niggas is on his dick cuz he's like this OG california rider, the cops never knows its him doin the killings until at the end where he snitches on himself through rap music ala x-raided and gets the death sentence
PS: take the idea ill sue your fucking pants off.
