Another week, another mass shooting. Time and time again, partisans wait to haul out another gun control argument or demographic blame. At this point, we know we have an epidemic, and as we’ve seen with the Parkland, Santa Fe, and Sutherland Springs shootings, there are almost always glaring, social red flags that indicated that the perpetrator was deeply troubled long before their massacres.

The Thousand Oaks shooting was no different. When the media first reported on the bloodbath, which killed 12 people, including a police officer, one of the first pieces of information publicized was that the killer — who I will not give the dignity or respect of naming — was an ex-Marine who suffered from PTSD. However, his problems clearly predated his service.
