I’m curious as to what, if any, common patterns or parallels can be drawn between Robinson with Crooks and Mangione. All three under thirty males (that is why I leave out the much older Routh) of documented above average intelligence and coming from seemingly good family backgrounds and no (known) prior criminal acts. Was there a common but, as yet, unrecognised, pathology at play? Or was it simply a matter of failing prey to the extremist and banal populism that leads to amoral and nihilistic thinking and, in these three instances, an immoral criminal act with tragic consequences? I don’t know.
