I have family that lives in Fairfax. It's generally considered a safe neighborhood, mostly new families with young kids. My brother caught 3 guys trying to break into a few houses and a BMW on the street where my sister lives. They also had burglary tools, a couple boxes of ammo and a loaded .38 in their car under the seat.
So as we all know, your so-called "safe neighborhood" may not be as safe as you think. Hell, we've had a few car break-ins in my neighborhood recently, which is unheard of.
On an unrelated note, I hate being 22 and looking like I could pass for 17.
