Continuity mistake: At the end of the shot where Al Neri shoots Emilio Barzini's bodyguards, the one on the right is still in the process of falling and hasn't hit the ground yet before it cuts, but in the next shot, he's already on the ground and not moving.
Continuity mistake: When they leave to kill Pauli it's light outside, when they are driving and Clemenza says that they to get more mattresses it's dark outside, when they stop to kill Pauli it's light again.
Answer: First, Clemenza kisses Michael's ring, then Rocco Lampone. Al Neri is the one who closes the door, but he is not shown kissing the ring.
