This is something I recall watching as a kid with my parents, so I’m assuming was 80s or earlier (60s thru 80s, not sure of the year).
The only thing I recall is there was a blind guy, and there was a scene involving the KKK. In the scene the KKK had someone who they were going to abuse, so the blind guy follows a rope outside while armed with a handgun. The KKK distract him by throwing rocks and the blind guy shoots at where he hears the sounds.
When I try to use google to figure out the film title, all I can find is references to the Chappelle show skit about the blind black Klansman.
