Stealing signs is fine and accepted if it is ONLY being done by members of your 25 man roster or any coaches in the dugout/on the field/in the bullpen. I assume they are accusing the Brewers of doing something in addition to this like using cameras in the outfield to look into Pit's dugout or catcher's groinal region and then relaying that info to RRR or directly to the batter. I have no idea if this is true but I assume this is the claim, not that the 3rd base coach is seeing the catcher's signs etc.
