Young Buck: I Have The Right to Shoot Crooked Cops Before They Shoot Me

Young Buck doesn't care if you think he's promoting violence against police officers with his new track, "The Get Back" ... he insists it's his RIGHT to take them out.

The G-Unit rapper didn't mince words on "TMZ Live", saying he will absolutely protect himself from "crooked police officers" and he's encouraging everyone else to do the same.

His song includes lyrics like, "Make these n****s load up and go kill a cop right now" ... and although Young Buck expressed condolences for the families of the Dallas officers -- he never backed off his violent message.

Sure sounds like he's echoing the 60's civil rights battle cry, "By any means necessary." Watch and decide for yourself ... he's also got a message for The Game and Snoop Dogg.
