The Question of whether any current shooters received treatment in the past has not been answered
Currently digging is needed on shooters. According to https:// www.massshootingtracker.org there were 57 mass shootings in November and December of 2017 and there have been 47 mass shootings so far this year.
As indicated in post >>462329 there are multiple shooters that are very problematic in terms of killing their parents, spouses and children for no apparent reason. That post listed 7 instances in the past 4 months in which shooters did not indicate any "typical" signs of mental illness, they simply murdered everyone close to them.
One thing that stands out with recent mass shooters is the geographic and racial diversity present among the individuals. Pic is relevant because the problematic shootings are not gang-related or "troubled people" shootings. In many cases they're inexplicable.
Almost like it's part of a scripted movie, with various shootings for no reason combined with all the crime that has people on edge, then spectacular mass shootings of innocents at schools. Kind of like a movie.
We're looking for common denominators for these people.
