I totally agree with Horsejody. Someone said that they can't make you go with a sheriff or deputy if you feel uncomfortable, but the fact is, they CAN. They can say take it or leave it. That's really all they're required to do under the law. If they're feeling irritated or spiteful over anything at all, all they have to do is follow the letter of the law. If they are really in sympathy with you, they might go an extra few inches to help you feel comfortable, but they are not required to, so plan to take someone unimpeachable.
A lawyer would be nice, no need to introduce them as one, just "this is joe smith" or whatever, of course, that costs money... but a minister or a reporter, yeah that works too. Like Jody said, impartial, not your best friend or sister who they can claim would lie for you.
