thats a mystery. its written he orderd frankcostellos tomb blown up . someone did blow it up in 74 same time galantes released from prison. theory was galante believed costello had him set up on the drug case. but phil rastelli is the boss in 74 till he goes to prison in 76. thats when he makes galante the acting boss. so i doubt galante was any type of problem with phil or the other families. i doubt he had any made guys in other familys killed he would have never been allowed to be acting boss
