Here's something that may have slipped by the main stream media's radar. And no wonder as to why. It has been fairly taboo to own a firearm that doesn't have a serial number, especially if it is obvious it was removed.
Granted, this is just a decision by some random Federal Court in West Virginia, but it does reference a SCOTUS decision made around June of this year in regards to New York's 'shall issue' type of permitting, basically banning tghe right to bear arms. So, I honestly think it is a stretch to say go ahead and file off all your serial numbers, lol.
As usual, any link you find for that SCOTUS decision is full of the usual anti-second amendment crap.
