"New York lawmakers are proposing a bill that could destroy the right to privacy and increase surveillance to an unsettling extent. The bill, spearheaded by State Senator Jenifer Rajkumar, posits that New Yorkers seeking to purchase 3D printers would first be subject to a criminal background check before the buy. This proposition poses substantial implications, particularly related to personal privacy and the potential to open the Pandora’s box of surveillance."
"Why the proposed law? The rationale behind the proposed legislation’s genesis lies in connecting the dots to the gun industry. Phantom weapons, aka “ghost guns,” are guns that lack identification numbers for tracking, and are, therefore, untraceable."
That's not the only thing someone might do with a 3D printer though.
