The legacy of MK Ultra lives on and it may be very costly for American manufacturers. Thank you, conservative Supreme Court.

The Supreme Court has denied Remington Arms Co.’s bid to block a lawsuit filed by families of victims of the Sandy Hook school massacre. The families say Remington should be held liable, as the maker and promoter of the AR-15-style rifle used in the 2012 killings.

The court opted not to hear the gun-maker’s appeal, in a decision that was announced Tuesday morning. The justices did not include any comment about the case, Remington Arms Co. v. Soto, as they turned it away.

Remington had appealed to the highest federal court after the Connecticut Supreme Court allowed the Sandy Hook lawsuit to proceed in March. In recent court filings, Remington says the case “presents a nationally important question” about U.S. gun laws — namely, how to interpret the 2005 Protection of Lawful Commerce in Arms Act, which grants broad immunity to gun-makers and dealers from prosecution over crimes committed with their products.

Remington manufactured the Bushmaster AR-15-style rifle that Adam Lanza used on Dec. 14, 2012, to kill 20 first-graders and six adults at the elementary school in Newtown, Conn.

Attention, businesses of any kind. If you sell a product that someone else uses in a crime, then you may be liable. Welcome to Connecticut, 2019. How conservative to step aside and let communists set national policy! Thank you for your service.
