Our government may not be perfect ( are there any in this world?) but I like to think we have processes in place to get to the bottom of the lies and cover up.
As to punishing those responsible, I really don't know what will be done. The Post Office CEO was awarded a CBE ( a relatively grand honour) during that period, for her services to the post office industry. She's been forced by the public to hand it back. Her successor handed back his bonus. The post office chairman was sacked this week. But all this hardly makes any difference to their lives.
I hope there will be some just punishment when the public inquiry is finished especially Fujitsu and they will be paying out big compensation to the sub postmasters. They've earned so much from this and other government contracts
