In Illinois, a Governor (not Blagojevic) went to jail because the State licensed a driver who didn't speak English, who ended up killing five children in a firey car accident.  I believe the driver was granted a license by a driving school which sold the licenses and contributed to the Governor's campaign.  It was licenses for bribes basically.  Therefore, there could be more than just a security issue.  The owner of the driving school could know persons in high places.
