Take another ex; Shakib was not out today but the umpire gave him out. Does that mean ICC deliberately helped Pakistan? No, it was just a dumb call from the 3rd umpire. No one making any fuss about it. Hope you get the gist.
Off-the-field politics is a different matter and you like it or not, it's there to stay due to a power struggle but when teams are playing or competing on the ground, ICC can't do shit.
Do Umpires make mistakes? Yeah, they do and it's bound to happen, sometimes decisions benefit one team sometimes the opposition.
Fans and experts have a choice, keep playing the victim cards/look for conspiracy theories or simply move on. The majority opt for the latter.
I understand the point that you are making. I am definitely not opposed to anything that you have said. However, I have not seen this type of mistake being made in any other sport, at least not recently.
Especially with all the technology available right now it is quite surprising that mistakes like this are being made in cricket!!
I agree that mistakes can be made. To err is human. But when you have the appropriate tools available, you should not make mistakes, that's what I believe. I literally do not understand how a third umpire can make mistakes. There is an unwritten rule that if something is 50/50 the benefit of the doubt goes to the batsman. But we also see things happening the other way around as well.
I don't remember many dismissals in LOIs but I saw a fair amount of dodgy rulings in Test cricket. I won't go into details as it's time-consuming but I would say, the tech is not 100% correct but at the same time, it's the best we got.
Also, cricketers should be aware of the rules, even during crunch moments. Unfortunately that's not the case right now.
