Old story
It is the same tired old story from a couple of years ago when the "Ban the .50 cal, it's the terrorists weapon of choice" started. The Brady bunch and some of their ilk said that Ronnie Barrett sold Bin Laden and his cronies(Al Qaeda) a number of rifles. I don't remember how many, maybe 25. As it turns out Bin Laden's folks did end up with a number of them. It also turned out the rifles were legally purchased by the federal government, who then gave them to "freedom fighters" to fight the Russians in Afghanistan. Guess who those freedom fighters turned out to be? Luckily for Barrett, he still had invoices showing the disposition of those weapons(for once all that paperwork was a good thing) and the investigation went nowhere. So now they trot it out on the news every once in a while to aid in their continued pursuit of banning all guns.
