If there were a scale for how weird/crazy/irritating a public defender's client behaves, I would put money on Chris being close to average. One standard deviation or less.
Same goes for any public service which deals with the lower socioeconomic strata of society. Chris does not stand out.
I did six months in a job based in the main reception of an inner-city hospital. People turning up with DIRTY CRAPPED items of clothing was a daily occurrence. Same with illiterate people. (This was in the UK).
Then there was the guy in a wheelchair who'd strapped a bunch of aerosol cans to himself, doused himself in gasoline, and was going to light himself on fire if we didn't respond to his incoherent demands.
Chris is no special kind of exceptional. He's exceptional in a very mundane way. Maybe the PD might find him a nice break from the gang affiliates and the people who think their dog is the Archangel Gabriel?
