> A slow-acting virus, like that of scrapie in sheep, is introduced into the human body via the tattooing needle and makes its way to the brain, where within a few years it causes the afflicted to steal cars, burgle houses, and assault people. I first formulated my viral theory of criminality when I noticed that at least nine of ten white English prisoners are tattooed, more than three or four times the proportion in the general population. The statistical association of crime with tattooing is stronger, I feel certain, than between crime and any other single factor, with the possible exception of smoking.

Thank you for this.
