Actually, Johnson survived but was left paraplegic. The agent in question ended up spending 20 years in prison for his blunder.
Yes. The 'CIA did it and then pulled the merely paralyzed Johnson out and hid him in an undisclosed location for decades' conspiracy theory has apparently reached even hereThere would be lesser conspiracy theories.
OOC: Why you are messing this? OP said that LBJ was killed. So I don't understand that.
Post assassinations Attorney Gen RKennedy did everything possible to make public Johnson's past. Even tho Kennedy stepped down as AG in 1964 the revelations on LBJ had taken on a life of their own. The successful prosecutions of his former associates were more of a trial of LBJ as them. By 1967 his reputation was beyond the ability of any revisionist to salvage.
OOC: Johnson had some pretty grimy areas. It isn't that hard to not like him.
OOC: What revelations? That he was secretly pro-civil rights?
