Professor Edward Dutton, human biodiversity expert, has given an interesting analysis of the US shooting phenomenon. The essence of his argument is that most of the shooters were schizophrenic. As this mental illness generally shows up by age 25, he suggests banning guns for ALL people under the age of 25, as well as having rigour mental health checks, so this will sort out possible shooters. This is something which sounds plausible at first but with reflection is not so plausible and is in fact a liberal-gun grabbing policy. I take it that he would ban all schizophrenics, however mild and medicated from firearms ownership? Clearly this would be struck down under the 14th amendment, end of story.
