It may just be me but after reading this it seems CA and more so James Sutherland and not for the best interest of Cricket in Australia but just trying to self promote themselves.

As was commented on by others, there was never anything wrong with our cricketers ethics while they were winning. Only after a few incidents, one of which has been admitted to being caused by the other side, some how now there is a long term ethical problem within our Cricketers.
I feel the ethical problem really lies within CA and maybe more so James Sutherland for their whole handling of the ball tampering saga. Prior to any internal investigation the three 'offending' players are guilty and thrown not just under the bus but to the media scrum without any preparation, legal or otherwise and definitely with no ethical thought given to the damage it created. The punishments handed to the three 'offending' players as has been reported by others is well and truely over the top of what has previously been handed out. Typically previous issues of ball tampering have resulted in being dropped from A test, not 12 month bans.
But yet the ethical issues are that inherently bad CA has to get an outside group, The Ethics Centre, to conduct the review into its organisational culture in the wake of the ball-tampering scandal. I guess the review will not include James Sutherland or other board members of CA.
