White Extremist Ideology Drives Many Deadly Shootings
White extremist ideology has been linked to some of the deadliest active-shooter episodes in the United States in recent years, showing the potential for intense violence among adherents who congregate online to cheer on racist attacks.
The suspect in the shooting rampage on Saturday at a Walmart store in El Paso was the latest to promote his ideology with an anti-immigrant manifesto posted minutes before he opened fire, killing 22 and injuring dozens more.
