I don't think such things are actually quantifiable... trauma, pain, and suffering do not have a dollar amount... the cost of treatment might carry a dollar value, but you can't quantify someone's suffering. It invalidates their human experience.

I understand that and it is not right, but people who enact policies and can fund programs might be more receptive to this type of framework over any kind of emotional appeal.

I disagree with the finite "lifetime cost per victim of $122,461" which is stated as including "criminal justice costs, property loss or damage, lost work productivity, and short-and long-term physical and mental health treatment for victims" (CDC). While this is an area that is different for each individual, it is bound to be more costly than that. It assumes once (listed line items) are accomplished, the victim is good to go. It is also a disingenuous, even futile, comparison to what 'could' be spent on education and prevention -- again which agency will support spending that much? A victim will likely re-live the experience for the rest of their lives, and, no matter how much therapy helps, or the individual's resiliency, any other threatening experience could spiral the victim back to square one. A very hard issue to tackle.

Agreed. The human costs are often discounted. I know the organization I've recently been hired to consult for works on prevention and education, as well as disseminating effective counter narratives in the hopes of preventing radicalization and terrorist behavior. This organization is also developing intervention methods with individuals who are at risk of becoming radicalized. I think that speaking from within an accepted neolieral paradigm by framing things economically can be persuasive in certain audiences, but addressing the societal issues that produce terrorist acts requires a more humanistic, preventative approach.
