Some of these shooters are plain bat-wing crazy. Others -- having watched thousands upon thousands of killings in movies and on TV -- believe mass killing to be a form of self-expression. Movies and TV don't show the real mess, the pain, the heartache, lawsuits, and destruction of the families after a shooting. What TV and movies do strive hard to show is the killer's rationale and frame of mind. The shooter is thinking about how bad or mad or sad HE feels and how good it will feel to lash out in a big way and finally get some revenge and attention.
