One notable exception to the general rule about crime in largely homogeneous communities that throws a wrench in the works is: The Wigger.
Whether you're in a city or some little town on the ass end of nowhere, you'll find The Wigger. A white guy that thinks he's black and has adopted many traits of 'black culture' for his own, especially the ghetto shit. Usually found wearing a snapback logo cap, fake 'gold' chains, stained white wifebeater, some hoodie with garish patterns, cargo pants and DC shoes. Typically has one of the following tattoos: a marijuana leaf, a teardrop, 'only god can judge me' or the name of some girl he dated before he dropped out of high school, often found on the neck. Also sometimes has dreads and a shitty goatee.
The Wigger is a real wildcard in terms of crime in predominantly white communities. At best, he'll be a minor nuisance, driving around in his beat-to-shit Honda or a maroon Beretta, with an obnoxious rattling subwoofer in his trunk blasting shitty trap music so loud that you wonder if the vibration will rattle his car apart since it's currently making framed pictures go crooked on your walls when he's parked on the street. At worst, he can be just as criminal as anyone you'd find in the ghetto, with an even worse demerit of being a poser. You'll usually find him dating 16 year old girls [at 34], spraypainting his rims some stupid color, and getting bitched at by his mom to get a job while he drinks Busch Light.
Get enough of these assholes and you'll see crime rates go up exponentially. Every now and then they get pulled out of the 'hard' lifestyle and you'll find them at an AA meeting, usually after they finish their third stint in prison, whereupon they suddenly find Jesus and start a skateboarding youth group despite being way too old to take a spill on a skateboard and get back up.
