...I've been thinking about this...and maybe you could try the following.

...secure the services of an attorney and have him draft a couple of documents for the sheriff to sign...the first stating that he fully acknowledges the fact that he is personally denying you the right to protect yourself while in his jurisdiction.

...second form states that he personally guarantees your personal safety at all times when you are in his jurisdiction...

...after lying awake a few nights worrying about the liability he has subjected himself to...he might just issue your permit so he can get a good nights sleep...
