It's an excellent film, and it's the story of how he got started and ends with his case in front of the Supreme Court.
The killer did kill the guy that was with Larry at the time. My memory is fuzzy and Google is so very far away, but I think it was his lawyer and that it happened outside of a courthouse. I seem to recall that he was going to court on a free speech matter and that the killer hadn't specifically started off with the intent of killing Larry, he just happened to be there around the right time so added Larry to his list of folks he felt needed killing for promoting interracial relationships.
Obviously the shooter was both insane and a racist. I seem to recall Larry making statements about leniency towards the shooter. There's a movie about it and several documentaries. The movie features much nudity, but the documentaries are much more tame.

Not the kind of wikipedia entry I was expecting at all.
