David,

This sounds like good police work to me, not COIN. I thought we borrowed a lot of community policing tactics to inform our COIN doctrine, so if the police are using COIN doctrine to inform community policing efforts, maybe that means the police let this skill set erode over time? If so, why?

Regardless the outcome appears to be positive, so I'm not criticizing the approach, just trying to learn why the police needed to borrow from our COIN doctrine to learn it? Maybe budget cuts reduced police manpower to the point community policing wasn't possible? Maybe the increase in deadly engagements with gangs, made it impractical?
