Read about LAPD’s textbook response to an outdoor active shooter here
Since the Columbine massacre in 1999, many police and sheriff’s departments have trained for rapid responses to indoor active shooters. Fewer have explored the options and training for outdoor active shooters, although the differences between an indoor and outdoor active shooter are significant (and are also different from a sniper attack). I’m not an expert on law enforcement tactics, so I won’t be detailing best practices here. What I am concerned about is the need for additional training for law enforcement and guidance to the public regarding outdoor active shooters.
It’s not a surprise that LAPD responded so well to this most recent outdoor active shooter since the LAPD experienced one of the most notorious outdoor active shooter incidents in 1997 when two heavily-armed bank robbers began an outdoor gun battle with police (see North Hollywood shootout training video Part 1 & 2)
