A few comments on the OP and obsevations and opions that are mine.
Many Veterans are homeless. What a national disgrace...
Many Vets have no real "outreach" or means to travel to such help.
"Lock 'em up" is a draconian knee-jerk reaction of people whom I suspect have more serious issues of their own...I agree with empathy and "putting yourself in their shoes" to gain a better intimate perspective of their situation.
Crispin is not a name that I'm currently familiar with, nor the theory proposed. However, this is "right up my alley" of current educational endeavors and I will soon familiarize myself with all of the principles involved. Is this body of work published and where?
My initial opinion is that-
1) There are many types of mental impairment.
2) Very few lead to negative socio-behavior.
3) The people who "snap" and go on these rampages almost certainly all have different disorders.
Including physiological impairments. Certain markers should be flagged and examined, though....
4) "Prediction" of such tragedies is at best a coin flip, due to:
a) a misunderstanding of mental illness among the general public
b) a lack of funds to study and further understand that Freud or Jung may have nailed it 100 or so years ago, but dynamics of social change MUST always be taken into consideration.
5) Placing the blame of the actions of a person, bent on destruction,
upon an inantimate object, is purely reductio ad absurdum.
My Best,
Scott
