I'm remembering the assasination of Thomas Wales, assistant US Attorney for Western Washington, on October 11, 2001, one year after the World Trade Center bombing and just as George W. Bush appointed John McKay to be his new boss.
Liberal Wales was responsible for the prosecution of white collar crime in Western Washington and was becoming quite well known for his community work, including his leadership of the Queen Anne Community Council. As I recall he had been with the US Attorney's office for 11 years. According to this wikipedia article Wales was a roommate of Joseph Patrick Kennedy in prep school - not sure if it was before or after the assasination of Robert.
Press speculation has centered around the theory that it was a gun rights activist who shot Wales as he also led the State gun control group, Ceasefire.
There never has been a single identified suspect for this theory - and that Mr. McKay's older brother, Mike held the same seat during the Bush I term and is currently engaged in the business of white collar criminal defense. Also worth noting is the prevalence of criticism of inappropriate government funding of companies controlled by the Downtown Seattle legal establishment by Seattle neighborhood groups.
This is just speculation, but the criticism of the Seattle legal establishment being unable to find a killer most likely among its midst holds up in other areas as well.
