Agreed. It would have saved alot of people alot of grief. I believe at the time, he was being protected by Tip O’Neil.
I believe the lesson Murtha learned from that was to be more careful on the way to go about benefitting from graft. He has learned just how far he can go and how to avoid being directly connected to illegal activity.
In the years since abscam he's gotten more arrogant as the years have passed. Lets hope he got careless on dealings with PMA the last few years thinking he was too good to get nailed, it will be only too good to see him in a federal prison.
