Abstract

630 Terrorist-Mass-Murdering-Spree-Shooters are compared with 623-controls and separated by 16-Questions with a=.846, p<.01, AUC= .704, p<.01 that are: (1) homicidal? (2) suicidal? (3) stressful-life-event? (4) handgun-many-weapons-access? (5) violence-planning-preparing? (6) revenge? (7) eliciting-others-concern? (8) intent-leakage? (9) criminal-misconduct? (10) grievance? (11) random-violent-behavior? (12) threatening-victims? (13) dead-male-victim? (14) targeting-person-school-work? (15) student-professional-work-relationship? and (16) student? Before killing, terrorists come twice to courts-police, doctors-hospitals, schools-universities and human resources and are not diagnosed as dangerous due to error-prone current ways. In Study-1: 370-workplace-shooters (1968-2021) are contrasted with 370-controls using logistic-regression (F= 134.64, p<.01, df = 13/726, R=.84, p<.01, R2=. 71, p<.01 resulting in 14-Questions: (1) homicidal? (2) intent-leakage? (3) stressful-life-event? (4) revenge? (5) many-weapons? (6) elicited-others-concern? (7) criminal-misconduct? (8) threatened-victims? (9) dead-male-victim? (10) targeted-workplace? (11) professional-work-relationship? (12) suicidal? (13) random–violence? In Study-2: 9-spree-shooters are distinguished from 12-homicidal and 24-control adults showing a “7-point-violence-profile on two scales: (1)[Ask Standard Predictor of Violence Potential-Adult Version] violence (F=17.48, p<.01); and (2) the Minnesota Multiphasic Personality Inventory, Second Edition [MMPI-2] F (infrequency) (F=92.15, p<.01); L (lie) (F=13.13, p<.01), (3) D (depression) (F=37.76, p<.01); (4) Pd (psychopathic-deviance) (F=44.66, p<.01); (5)Pa (paranoia) (F=50.58, p<.01); (6) Sc (schizophrenia) (F=53.85, p<.01), (7) MacAndrews alcohol (F=42.01, p<.01); AAS (addiction admission) (F=57.34, p<.01). Looking from 1968-2021 at the insurance industry expense, there is the workplace-shooter loss = [$1,418,945,589.60 (370-shooters @ $3,834,988.08) + $4,053,582,400.56(1,057-deaths @) $3,834,988.08 + $37,556,154.24 (1,112-injured@ $33,773.52)] = $5,510,084,144.40 + [higher-insurance-premiums [$5,510,084,144.40 x 1.3 =] $7,163,109,387.72 = $12,673,193,582.12.
