Baseball Instant Reply

Baseball should start some form of instant reply. As I'm sure most of you have seen by now, the umpires have been atrocious this postseason. It all started with them not awarding Brandon Inge first base after being hit by a pitch. And then with the numerous missed calls in the Yankees and Angels game last night, this has been enough.
What are the arguments against instant replay? There are two reasons behind it. One of them is that it would cause games to take too long. Are you kidding me. Last nights game took 3:38 and they got all the calls wrong. So would anyone be upset if it took 3:45 to get all the calls right?
The other argument is from the traditionalists. Who think baseball should be left alone. I'm sorry that this isn't 1956 anymore with the Yankees and Dodger playing a subway series, with Mickey, Whitey, Yogi, and Jackie. Those days are over. So maybe we should catch up with the times. And does anyone really think care about the purity of the game. We've found out for the last few years, that most of baseball spent the last 15 years cheating.
So why doesn't baseball get this one right. Baseball would be the easiest sport to do instant replay in. You don't have to use it for balls and strikes, but use it for everything else. You don't have to do it like the NFL does, but do it like the NCAA does. Just have a guy up in the booth watching every play. If there is a questionable call, just ask him. That way we can get everything right. I understand the baseball has survived 100+ years without it. But baseball also survived without blacks, lights, and even airplanes. But when it was time to take advantage of those things baseball did. Well, this is baseball's time to add instant replay.
