Instant Replay

I have never understood why instant replay is not used in all sports. And in some cases it should be used more than is currently permitted. Yesterday, The Twins lost a wild game to the A's 14-13. However, the final out was recorded when Michael Cudyer tried to score from 2nd on a wild pitch. He was safe by a mile, but was called out. Cudyer foot had slid literally across the entire plate before he was tagged. If instant replay was permitted for base running plays the call would have been overturned and the game would continue. But, since there is no replay the game ended on a horrible call. Its always been amusing that people say human error is part of the game. In what other situation is that an acceptable excuse. If I failed a test and my mom asked me why I failed and I said because of, "human error," I don't think that would be an acceptable excuse. Or trying using, "human error," as a reason you messed up on a business project and see how your boss responds. Soccer is another sport that needs to adopt instant replay. A terrible call has already decided one world cup final, and it could have been prevented with instant replay.
