I've read Tookie Williams biography, and while he always denied having committed those crimes, the evidence is pretty overwhelming against him. It's should also be noted that he was admittedly addicted to PCP, and he admitted to smoking the days of the killings. It's been known that PCP can cause people to commit acts of aggression that they do not remember and wouldn't normally do. While I liked the guy personally, I am quite sure he was guilty.

Washington on the other hand was not nearly as important as his life went on. He was killed in cold blood, likely by a fellow Crip as BlackFamily noted, and his killer was never caught.
