With mass shooters there is an irresistible urge to tie their behavior to politics. Democrats pounced on the El Paso shooter, who seemed to lean right. Republicans pounced on the Dayton shooter who pretty clearly leaned left. All such pouncers are wrong, or maybe right for the wrong reasons.
Our politics truly are polarized, too many partisans really enjoy their hate. Mix in the sad, confused loners who are essentially suicidal but want their deaths to “mean something” and there will be massacres and politically tinged manifestos.
Unfortunately for those who would try to prevent massacres, there are undoubtedly hundreds, maybe thousands of such loners for every one who goes postal. We’re not talking “needle in haystack” difficulty, this is “needle in a bushel of needles” impossible.
