The world awoke Friday (July 20) to the horrible news coming out of Colorado that armed gunman James Holmes entered a Friday morning showing of 'The Dark Knight Rises' in Aurora, Colo., tossed a canister of tear gas into the showing, and while wearing a gas mask he proceeded to fire random gunshots into the crowd.
