One thing you can do is go to the web sites for the various state Attorney Generals. That will tell you how many licenses have been revoked. While that won't tell you specifically how many were revoked for having committed crimes You can bet your "bippy" that everyone who committed a crime was revoked. In my state of Kansas for example only 11 have been revoked and 5 suspended. I don't know the difference between being suspended and revoked but I do know there are reasons for both which do not necessarily mean they committed a crime.
