I am the authorized instructor that certifies that he is qualified under the state laws to receive his "shall issue" permit, so I am very interested in the situation.
I, too, am a guy that likes to stay under the radar, and I personally would not poke the bear, regardless of how illegal the bear is being.
That said, this is a very interesting situation. This is a "shall-issue" state. If the sheriff's office does anything to illegally interfere with his permit, I see the probability of serious repercussions from the state courts, though that may be a long process requiring the services of good lawyer$. It is state law that the sheriff's office cannot restrict you from openly carrying your firearm while conducting your lawful business in their public building. They get away with breaking this state law every day because they have a badge. Most of us choose not to pick the battle because there is no penalty clause in that particular state law and it would be a long hard fight for practically zero personal gain and lots of powerful enemies to be made.
The sheriff's office also illegally disarms all the CCW instructors when they have their annual meeting with us. You have to be checked off a list to enter, yet you are still illegally told that you cannot be armed. Do they really distrust us? No, it is obvious that it is a simple illegal power play that they will do because no one will stop them from doing it.
I may not be the most articulate person, but I pledge to be a free expert witness in any trial for someone who attempts to assert their rights.
