Disagree with you there there was alot of reasons Long John could of got whacked besides moving back in on his rackets.
1. He killed alot of people himself or ordered them killed some with alot of connections so could have been revenge
2. He was blamed for the crow flipping and that put alot of people in jail. Crow might have flipped before Leonetti causing Leonetti to flip Crow said himself he flipped because of him
3. He was starting trouble with a very connected possibly made lawyer because of his kids sentence guys name was Simone and when he got out of jail he was starting trouble with him
Not sure who reported he got hit for moving back in on his rackets dont think anyone knows that for sure
One thing is certain though Long John was a huge money maker Philly guys would have kept him around for that alone
