The murder of 12 people at Aurora’s Cinemark theater shocked the world in 2012. Today, a jury decided that the theater chain could not have foreseen an armed attack on a midnight screening, the Denver Post reported.

James Holmes was convicted last year, but survivors and victims’ families argued in this first civil lawsuit that Cinemark could have slowed the shooter with armed guards and alarms on doors.

A finding that Cinemark was liable for the shooting likely would have forced significant changes to theater security policies across the United States. The company had argued that it couldn’t have implemented any security measure that would have stopped Holmes and his arsenal, the Associated Press reported.
