This man's guns were not confiscated. The police did him the favor of calling him first to inform him that they would be confiscated.
Mr. Mayer then took his sidearms to a friend's house and his long guns to his local FFL to lock up. The JBTs did not get their hands on his personal assets.
Why an FFL? Now they are registered and tracked.
Screw that I trust nobody with any of my assets outside my immediate family. Is anybody smart enough to just hide anything anymore and shut the heck up until they need to use them?
