Michael Carneal was 14 years old when he walked into a prayer group in Paducah, Kentucky in December 1997, and began shooting defenseless teenagers with a stolen gun. See id. at 75. There were several tell-tale signs that this massacre was incited by a violent video game. For example, he never moved his feet during his shootings, and never fired far to the left or right; instead, he fired only once at each target that appeared, just as a player of video games maximizes his game score by shooting only once at each victim, in order to hit as many targets as possible.
