No. That is complete bullshi*. Please give me a link to where this is? If Paul was alone and asked Gotti where the tapes were then how do you know about that? John was greedy. He killed Castellano to become Boss himself plain and simple. He didn't like Castellano and also Big Paul was giving him alot of shi*.

John should of waited his turn. John easily could of when to Carmine Persico as they were involved in drugs. Johnny G had other options and had alot of people. He could of even asked a drug dealer to kill Big Paul but he didn't. He gave Castellano and everyone else his message that he was the true boss and if anyone was going to get involved then look at Big Paul Castellano. I doubt he would of created a big history assassination over a bunch of drug tapes and if it was about drug tapes then I don't know why he instantly bragged about that he was boss, and waited outside the club to be congratulated.
