Sure the "independent Umpires" may be human and made an error or two......but what about the decades during which no Team could win a series anywhere on the sub-continent when "home umpires" were used?
Is it no wonder the world's best batsman, Sir Donald Bradman never toured the sub-continent?
All of a sudden, as happens in life, a few things go against you - and what's the response? - charge of to the ICC and make an official complaint.
If touring sides had done that over the period of "home umpires" officiating, there'd be no forests left in the world & the ICC would still be going through the paperwork!!
Don't be sore losers......simply because you can't "rig" the game at home any more....it's in the record book now - get over it.
