Yes, but there are more examples I could find of out of control sheriffs being arrested by state troopers, or city police than the other way around. the bigger police departments get, the smaller affiliated sheriff depts get, until they are mostly relegated to transport, admin, jail's, and transfers.  You have to remember the role the DA plays, the sheriffs would have to have the DA & judges on board with the plan. look into rio arriba county, local small town cops going head to head with large politically connected corrupt sheriff. They raid his office, serving warrants, and arrest him and his under sheriff for interfering with arrests then publicized the videos.
