At this point, the best outcome (**after** they catch and kill this killer) is for it to have been a terrorist and/or certified looney tune with a Ruger No. 1* single shot rifle, and that he tried repeatedly to buy it at gun shops and gun shows, but was turned down in 1998-1999, so he finally had to steal the rifle.
At least then we could ask why the Clintoon administration failed to follow-up and arrest the guy back in 98-99.
*Nothing against Ruger or their fine firearms (I own stock RGR), but it is the least threatening (in liberal minds) break-open single shot action I could think of.
BTW, RGR is a really good stock, and SMWS (Smith & Wesson) is turning out to be a decent one also.
A bit far fetched, but it'd sure be sweet to see. The anti-gunners would be so PO'd.
