When I was a teen, an IRS agent lived across the street from my family.
No one said anything to him about it, but everyone looked at him as though he were in the mafia. Which is closer to the truth than I realized at the time. People were a bit suspicious and standoffish around him. And he didn’t really socialize much.
He acted guilty because he was.
Of course, I was just a teen. Perhaps the adults didn’t think they were acting that way toward him. It’s certainly the vibe I got, though.
This was back before concealed carry “laws” were spreading around the country, and he was the only person I knew of who routinely carried a gun. Honestly, I don’t remember whether he open carried, but if he didn’t I’m not sure how everyone knew.
I’m in favor of everyone other than government employees carrying weapons. I am not in favor of anyone working a “job” that allows them to do things which are unethical (theft/”taxation”) or to do ethical things illegitimately forbidden to the rest of us (carrying weapons).
I knew at the time there was something not quite right about him and his “job”. Now I know exactly what it was.
