A second stratagem for neglecting probability that is sometimes applied at DHS is to devise a rating scale where probabilities of attack are added to the losses. Thus, as a Congressional Research Service analysis points out, to determine whether a potential target should be protected, DHS has frequently assessed the target's vulnerability and the consequences of an attack on it on an 80-point scale and the likelihood it will be attacked on a 20-point ranked scale. It then adds these together. Thus, a vulnerable target whose destruction would be highly consequential would be protected even if the likelihood it will be attacked is zero, and a less consequential target could go unprotected even if the likelihood it will be attacked is 100 percent.Congressfolks accept this kind of hand-waving because questioning DHS looks "weak," but what is the motivation for doing such shoddy analysis in the first place? Unless the president or DHS higher-ups are telling employees, "we want to spend $1 trillion--figure out how."
