Yeah, tough guy Paulie with his hand on a gun in front of the fbi.

Also noticed today after watching g2 for the 1000th time - noticed the look on johnny fontaines face when Mike presents the " offer " to appear in Vegas and for some of johnnys' friends to do so also - the look is almost like " I knew there would be huge favors asked ".

When barzini is walking through that building prior to bring shot by neri, he is all alone, no bodyguard, no witnesses. That would have been the perfect time to take him out. They could have had 2 or 3 guys in there with knives, stab him to death, walk out and nobody would have known what happened.
