This video probably won't last long, due to the fascist MLB lawyers, but watch what happens on a pop fly during the Braves/Cards game.
The umpires ruled the ball under the infield fly rule, and on a ball that ended up traveling about 200 feet, that call was clearly wrong.Story Link
And at the end of the video, you can see the debris thrown out there by Braves fans.
They ended up blowing another call later, on Chipper Jones's last at-bat. He hit a broken bat grounder to 2nd base, and the throw was errant, causing the Cards 1st baseman to momentarily leave the bag. I felt he should have been called out, but they ruled him safe, even after the STL 1st baseman got his foot back on the bag in time.
If I was a Braves fan, I'd feel bad that STL scored 6 runs and made more than enough plays to win the game. But I'd be hopping mad that a blown call halted any further progress at a crucial point in my team's rally. And if anyone agrees about the Jones play being mis-called, if I was a Braves fan, that's not how I want things to be 'made up' to me. Offsetting erroneous calls don't help the situation at all.
