Surely PA Consulting should immediately be sued out of existence. This kind of behaviour must be considered beyond negligent, practically criminal. I would strongly support throwing anyone involved in this into jail for a long time as a deterrent against future criminals. This is just unbelievable.
But, even though they got approval, they may have committed a criminal offence.
This data initiative is really important. They've got to do something to win back trust. Someone has to lose a job and someone has to go to jail (if a crime was committed).
