Riot-control Lessons for London from the LAPD

London has seen its worst unrest in decades. Los Angeles saw America's most violent and deadly civil disturbance in the entire 20th Century. It's dangerous to compare events in different cities at different historical moments, but there's one apparent similarity to what happened in London this week and what happened here in Los Angeles in 1992. When trouble began, the police were late to the action; looting and violence spread and went on for days. How would the Los Angeles Police Department respond now? Lt. Andy Neiman has been with the LAPD for 25 years, joining six years before LA's riots.
