I normally don't comment without reading the link and I will read the article, but I do want to point out that lots more people can 1) legally carry spray, 2) can afford spray and 3) are able to learn to deploy it effectively. It's easy for those of us that are experienced shooters to overestimate the ability of a person (including ourselves) to stop an attack with a firearm. Shooting, especially with a handgun, takes some practice.
