The video tape clearly shows the home plate umpire gesturing "out", based on the infield fly rule. (Sticking with the rule book, the umpire does not even have to make a call since the play is dead under these circumstances) And there is no longer a play to call interference on. The second base umpire may have interpreted a technical interference (though not apparent on the replay) but the moment the ball is hit in the air, which is before the runner returns to second, again, the play is automatically dead and the hitter is out. The crew chief has the authority to negate any other umpire call after the infield ball is popped up. What was lacking here was a pause, and an umpire conference to clarify this simple rule. Their failure to do this just adds to the bad reputation umpires already have, especially when it's game-ending.
