You can say a lot of things about Paul he was greedy and he wasnt a tough guy. HOWEVER he was a smart guy and tried to stay "in the shadows" which was probably the smart thing to do as a boss. The main reason the FBI were granted a bug in his house was because of Angelo's big mouth and the drug dealing from the bergin crew. I dont think it mattered that he didnt attend Neil's funeral because gotti and angelo had already started to put things in motion in september of 85
