This has been going on for a good while. In NYC in the 40’s many men carried regardless of the Sullivan Act. Vladimir Nobakov’s wife carried a pistol in her purse for their entire marriage. His father was killed in a bungled attempt on the life of Peter Miliuekof and she saw how fast such an event could happen even in ‘civilized’ Europe. When Vlad spoke publicly she always sat at the back of the hall and constantly scanned the audience. Smart and brave woman. Her ever so smart blabbermouth husband never had a clue she was doing the concealed carry thing. He would have had a fit had she told him.
If you carry, don't tell anyone. If anything happens, better to do 6 rather than be carried by 6. As an I.T. manager, I suspected some of my crew carried but never inquired. I questioned some as to why they wanted to go to sites in pairs when only one tech was necessary to do the job. They invited me to come along. At a site, with angry young blacks milling around, my worker said to me "Your job is to watch my back as I get the equipment out of the van into the worksite.". My worker was a young tough black guy who lived in the ghetto. I was in a suit, and quickly understood why one would want to carry protection. After that, I allowed them to go out in pairs without questioning.
