Connecticut’s Supreme Court ruled Thursday that the manufacturer of the Bushmaster AR-15 rifle can be sued and potentially held liable in the 2012 mass murder at Sandy Hook Elementary School in Newtown, Conn.
The Connecticut court said the suit could go forward under that state’s Unfair Trade Practices Act, a statute aimed at harmful marketing, in this case marketing not of the weapon itself but the use of the weapon as a potential tool for “offensive military style combat” by civilians, which is illegal.
