Was it ever revealed that Tommy HAD to "go" along with Paul... ie if Tommy for whatever reason didn't drive Paul that day, would the hit gone ahead.... Tommy was considered his most faithful loyalist and was a "gorilla" as described by Sammy. Taking out Paul and leaving the underboss alive would be very dangerous

Tommy would have lost no doubt without Paul around BUT he would still put up a fight what with his brother Joe and some of their guys...

"The fist" would effectively have to hit the mattresses

Abit like the 3 capos murder. The first meeting (planned hit) was called off because not all three turned up
