Neil had no clue, his bedroom was bugged. No where in the tapes did it suggest he had any clue of what was unfolding

As for Paul not touching Angie, u do realise Paulie was in serious trouble and possibly going away for life. Having a war was the last thing on his mind, it would have also bought too much heat during trial

The Gotti crew would have got dealt with after not necessarily with violence. We will never know. Either way, Paul would use the tapes to disband that crew and
break Gotti down to soldier
