Bobby boy went after the Kennedy's enemies and friends, namely the mob. After the mob got Johnny the presidency with the help of Daly and all the dead Chicago voters, Bobby reniged on the deal which caused Johnny to get what usually happens to those who cross the mob. Remember, the drag queen LEO Hoover refused to even admit the mob existed untill Bobby went on his anti mafia jihad while attorney general. BTW, no real honor there, just a cheap populist political show. The Kennedys have been in bed with the mob since before Joe even thought of fathering that collection of dirtballs he called his children, and la cosa nostra was offended when they tried to act like they weren't the scumbags they are.
