@kims A couple decades ago, I found an attack against master-keyed mechanical locks, my publication of which made locksmiths very angry. I got death threats, which was equal parts scary and hilarious.
A few months later, I attended, with some trepidation, a locksmithing convention at the Vegas convention center. I wrote up the experience, provisionally entitled “Fear and Locksmithing in Las Vegas”.
Sensibly, I promptly changed the title before showing it to anyone.
