AWTA.NOT OUT !!
This is where technology is so good. It wont ALWAYS tell you what the umpires dont know anyway but on many occasions it will. It doesn't have to be decisive 100 percent of the timet to be used. It is good if it can reduce the doubtful/contentious/bad decisions.
It is only an aid not a final decision maker. That is still going to be a human even if he is sitting off the ground.
ICC are you watching ?
Perhaps this should be tested out in an ODI or T20 match first. Or a Test if you want a test case.
