As mass shootings make headlines, one man who has spent years studying what it takes to get men to kill said it’s clear that violent entertainment is a how-to manual for many killers.
According to retired U.S. Army Lt. Col. Dave Grossman, violent media mold the character of their consumers just as military basic training conditions soldiers to kill. Grossman is a psychologist, author, and public speaker. Grossman said the media, especially computer games, normalize abnormal behavior to the point that injury and death are rewarded.
