By the way - I am actually one of the small number of people who can legally carry a handgun in the UK, and if I’d been anywhere near this and I’d been carrying, I’d have drawn it and gone after the guy.
And in all probability I’d be dead at this point. I think you are quite correct that it’s unlikely concealed carry laws, etc, would have helped in this case.
But the thing is, I’d have gone up against him with a fencepost if that’s all I had. And that would have been even less likely to work.
At the range today, I was next to a guy firing 3 inch mag slugs and buck shot out of a short barreled shotgun. I wouldn't have wanted to take him on with my Stoeger Cougar 9mm.
Well that’s very noble and courageous of you, but unwise strategy.
