Libel, I'm not sure, but I'm American so we have no such laws anyways.
DUI is interesting: its like randomly shooting into a crowd of people and just missing to hit someone.
There is a difference between going to jail for 4 years and just going bankrupt. The first you lose your freedom, the second you just lose your property but can at least keep living. Many people would never recover mentally from being incarcerated for 4 years, but many can recover from bankruptcy.

>"I think just banning him from investment-related jobs and imposing some kind of probationary oversight would be sufficient to keep him from reoffending."
Would the ban guarantee he could never re-offend, or would it just limit the scale of any potential future fraud?Given the level of his past fraud and allegations of possible fraud going back as far as the 70s imprisonment doesn't sound inappropriate to me.
The problem is with the wealth he probably has hidden somewhere. If not in prison, he would still be living a very rich life. He wouldn't need any job.
