His presentation was: Beyond the One Percent. The presentation looks at firearms ownership vs. firearms training. How many (or rather, how few) people actually participate in training. Why people participate in training, and why they do not. And what we as trainers can do to increase participation.
The presentation was well-received and I know of at least one high-profile group already putting Karl’s teachings into practice.
Even if you’re not a firearms trainer, there’s a lot of fascinating data about firearms ownership and training in his presentation. Well worth the read.
