Loved this, Paul, even if PHP is not one of my languages. Fortran was for 8 weeks in 1974, after the examn I dropped all efforts to learn computer languages. O yeah, had to MSDOS a while, but that hard time passed too. I hope you continue this analysis. It is very interesting. A few hypotheses: overrepresentation of male rioters, overrepresentation of members of extremist groups, overrepresentation of people brainwashed by FOX-like media, overrepresentation of hanger-ons, no 'blue' rioters ( apart from the embedded press). I know, I know, those characteristics are not part of the DoJ data.
