Apparently the video didn't show the umpires coming together to discuss whether or not anybody saw the batter get hit. This ejection came after Joe had already started back to third and got most of the way there.
If you convince the umpires to come together and discuss something like this, you should be prepared to get run if you go off the deep end (especially while gesturing) afterwards.
There's a cut at 0:20.
Watch at 10:20 of this:

Gesturing like that is going to get you run, especially in the Major Leagues. It's probably going to get you run from any game I work, too.
Of course this just lets the usual suspects get another dig in at Joe West for doing his job.
