Safe bet... Dem or Pub... the kid had a father that was by all rights.... a shitty fing father.
And yeah, tattoos on one's face are un-fucking acceptable to any father who gives a f about their kid's future.

You are trying to make this about tattoos (as opposed to the 'mental health' canard) that other right wingers resort to when one of these regular gun rampages happen.
Yes, those tats are a red flag that were probably not the first manifestations that this person has issues.
If we really want to fix societies ills, from single mother households to drug abuse to looting and shooting...The ability to control one's impulses and modulate one's emotional expressions is the earliest and most ubiquitous demand that societies place on children. Moreover, success at many life tasks depends critically on children's mastery of such self-control. Early self-control has a profound and lasting effect on one's life in adulthood. A 32-year longitudinal study indicated that possessing self-control in childhood (defined as 2–10 years of age) predicts physical health, substance dependence, personal finances, and criminal-offending outcomes in adulthood (i.e., there is a self-control gradient)1.

Certain societal groups seems better inclined in the teaching of this than others.
