I for one do not see a problem with Sheriff not being allowed to own a firearm. Most County sheriffs are politicians first and law enforcement officials last.
When was the last time you have heard of a Sheriff responding to a low profile call? Nope, that is for the deputies. High profile call? Sheriff is there in full uniform (dress or tactical depending on the situation) with at least 5 stars on his shoulders or collar.

Outside of major population centers here in Texas, happens all the time.
