Complain all you want (civilly, of course)
It won't matter. The Sherriff is acting within their authority, under existing law. I don't agree either, but that is the way it is. The only thing you can do is work to get the law changed.
And that takes influence. Political cronyism (read corruption) is as old as politics. In the USA, under our current system, we have a slim chance to beat that age old influence. But only a slim one.
But a slim chance is better than none. Don't give up the fight.
All else being equal (and it almost never is) bigger bullets tend to work better.
