Eric Thompson a Villian?

That's what you'd think from listening to the media. Thompson owns the company where the VT killer bought his weapons, where the N. Illinois shooter bought magazines & a holster for his Glock, and now where the PA gym shooter bought some magazines.

Now we see the anti-gunners and the media (but I repeat myself) attempting to vilify Thompson despite the fact that he's done nothing wrong.

Is the owner of a cutlery store responsible if someone buys a knife set from them and later uses it to stab his wife?

Is a car dealer responsible for cases of vehicular homicide or DUI because they legally sold a product to the person whose actions precipitated those events?
