Death warrant. You give up your advantage. Wish all LEOs could all carry concealed in plain clothes.
The Boston/Watertown bomber manhunt was rather enlightening.
On my old Farm, it was “private property with a public accommodation”, so I open-carried frequently. Especially when I was out on the old range with customers and friends. I had a lot of LEOs and Military customers’ and families who always wanted to shoot w/ me, and take a “tour” of the huge Cannon Safe, to see what new ‘goodies’ I’d acquired. They all got the “tour”, each time they asked, and got to shoot many of them. It’s a very different world here, now.
