This gets nuttier at every turn. The local sheriff has got some serious 'splainin' to do about why he knowingly allowed this guy to continue to illegally possess and use firearms. The county has some serious liabilities on behalf of their sheriff. Going after the sheriff himself would be all but impossible as he's an elected government official and enjoys nearly 100% immunity, even if he's completely negligent, and utterly inept and incompetent.
