I disagree with this. "During the party, Sonny destroys the camera of the FBI man, even though he could have just kicked the car. He spat on the ground not at the car." - I doubt that was even the camera mans car.

"When Clemenza, Rocco and Paulie are going on their drive through NYC, he warns Paulie: "Watch out for the kids while you're backin' out"" - Clem was just warning Paulie that his kids were behind the car incase Paulie didnt notice.

"Rocco and Clemenza are so scared, they run away like cowards and don't tell any-body." - No, I don't think Clem and Rocco would go and tell Tattaglia (or Barzini) that Paulie was whacked and would brag about it. They would leave quickly before cars drove by and didn't become a suspect.
