I'm sure we return the favor here.
Well, some people DO return the favor:
The late Tookie Williams:
"'Killing All White People' Once back in Los Angeles, Williams asked if anyone wanted to get something to eat. When Sims asked Williams why he shot Owens, Williams said he "didn't want to leave any witnesses." Williams also said he killed Owens "because he was white and he was killing all white people." (TT 2189, 2193)."
