Alrighty, then... I downloaded the issue and read the article.
When in the company of trained comrades, I'm slightly liberal on some safety issues. Not willing to delve into that hornets' nest at the moment, I must say I would have left the course LONG before I could have observed as many safety violations by perfect strangers as were witnessed by the author.
After reading such an article, I'd research the credibility of the author... a report on a firearms course like this is pretty unbelievable!
