 He is the father of John Robert Blakey, a United States District Judge of the United States District Court for the Northern District of Illinois, who was formerly chief of the Special Prosecutions Bureau for the Cook County State's Attorney and a special assistant attorney in the United States District Court for the Northern District of Illinois.Under the close supervision of Senator John Little McClellan, the Chairman of the Committee for which he worked, Blakey drafted the "RICO Act," Title IX of the Organized Crime Control Act of 1970, signed into law by Richard M. Nixon.While in law school, Blakey edited a student note on the unsuccessful prosecution of attendees at the Apalachin Meeting, which first sparked his interest in organized crime; he also wrote a note that analyzed civil liberties in the union movement.
