JJ wrote an excellent comment in a previous post:
The technology for in-game testing is almost upon us, but it will be blocked by the usual suspects. But if the ICC ever has the balls to implement it, then several careers will instantly end, and records will have to be erased if they are serious. That's why it will never be permitted.
But the truth is that one day it will simply be possible for anyone to run a video image through a computer and do it themselves. When that day comes it will be very, very embarrassing indeed for some bowlers and cricket boards.
Jumping to conclusions between the lines, I suspect the ICC knows it.
The ICC chief executives committee meeting in Melbourne as part of the governing body's annual conference, recommended that ICC management review the current process for reporting, assessing and clearing suspect bowling actions, while also suggesting that wider powers may need to be applied to allow the monitoring of suspect actions beyond the end of formal testing.
"The message out of the cricket committee was there's enough bowlers with suspect actions that should be being scrutinised, that probably haven't been," Geoff Allardice, ICC general manager of cricket, said. "By scrutinised, it just means they're being tested whenever there are concerns raised. At this stage, it's been pretty quiet for a couple of years. The cricket committee was of the view there are some bowlers operating with suspect actions that should be scrutinised a bit more closely."
