may umpires biased

Yes, I am totally agree with you that now a days there are a lot of wrong decision given by the umpires, and the media criticize became more when the errors are against some favourable players. But one thing we must remember that Umpires are also Humens. So there is scope for errors. With the latest technologies we may know about the errors in the latter stage, but on the field it's quite difficult to give 100% accurate decisions. So I think we must have to bear it. and at least we have to keep faith on them.

I think many umpires are bised toward certain players. It is a known fact that there are few umpires who mostly give wrong decisions for which many of our indian players are victimiswed.
