Well, I was held up at gunpoint in an off licence in Pyrford in Surrey, and you dont get any more quiet than Pyrford! Its basically a little home counties village and the most trouble you usually get is the odd yobbo on a scooter.
After that experience, I'm all for concealed carry and home defence. I wasnt before, but I sure as heck am now! You're right, there are some nasty pieces of work out there.
Take care Jimmy, and stay safe.
All the best,
Stu
