The article is very obviously making a point against gun proliferation. It's not about "some or any gun regulation", it's a piece intended to alarm readers about the proliferation of guns, even alluding to the recent Sandy Hook school shooting. The paper published an article warning about the dangers of gun proliferation, then hired gun men to protect itself, creating more gun proliferation. That's the irony. It is a "do as I say, not as I do" situation.
