Josh Sugarmann, executive director of the Violence Policy Center, seems to have a simple job: find the hint of a fact, and abuse it to craft bizarre anti-gun fiction. Such was the case in “The Collapse of the AR-15 Assault Weapon Market,” Sugarmann’s recent Huffington Post article. The article brought guffaws of laughter or outright mockery from gun bloggers, who found the closure of KBI/Charles Daly not to be evidence of a market in decline, but an example of a company with a questionable reputation for quality failing to survive even during a seller’s market.
