On Sunday, the police identified the shooter as Eddie Ray Routh, a 25-year-old veteran with a history of mental illness who had served in both Iraq and Afghanistan. The police offered no information about a possible motive.

Likewise, not all those who go on a shooting frenzy have a history of mental illness.
