Yes sign stealing goes on. It's a part of the game. Man on second you're gonna have sets of signs. The problem is they used a feed from the camera in center field to the dugout tunnel, where a Astros employee was charged with setting up the AV system on a folding table, and hurriedly breaking it down after the game, leaving only a few wires coming out of the wall. I don't exactly think that's part of the game.
