Chantilly's Serenity Shattered - 1 officer dead

Just talking with a friend about these events. Yaknow, I think there was alot more crime in PA where I lived but down here, it seems like when something does happen, its a pre-meditated and huge issue.... not just a random drive by and stuff such as that. But then again, we're so close to the political center of the nation that it I guess pre-meditation makes sense. While they dont have a motive in this shooting, it sounds like something was planned that failed. For reference, Chantilly is where my church's office is.
