That LBJ was responsible for the assassination was the firm opinion of a former Dallas County deputy sheriff I was working with in 1985 who had been on duty Nov. 22, 1963. His absolute confidence in that opinion has always stuck with me. His attitude was “Well, everybody in the department knew but were smart enough to keep their mouths shut”. There are as many plausible suspects to mull over, including Oswald as a lone Marine Corps trained marksman turned Communist, as in a whodunit board game. Is it possible and believable that LBJ could have been involved? Sure.
