Why do we owe this man a living?

Stan "Pampy" Barre, a member of Morial's inner circle who pleaded guilty in January to plotting to skim more than $1 million from a $64 million, 20-year contract for energy management services signed in the last days of Morial's administration in 2002.

Why does he still have any public contracts? Seems to me the first thing to do is void all of his contracts and bar him from ever participating in any public contract ever again. Hopefully that and restitution will be part of his sentence
