The message is clear: Non-Christians will not get a fair hearing from anyone who works here. This is a Christian facility through and through.
That Sheriff is unfit to hold office. He is not rational. He is a Christian supremacist.
Nobody is telling the Sheriff he can't believe in Jesus, just that it's illegal to promote that belief through his office. That office belongs to all the taxpayers, not just the Christians.
I'm really bothered by the description of group prayers before executing search warrants. Not only is anyone coming into the office clear on how it's a Christian-only organization, so is anyone who works there. Statistics suggest that at least some deputies aren't full-on believing Christians, just going along to get along.
