Just because people engage in mass shootings, bombings or the use of vehicles to kill DOES NOT mean they have a mental disorder. What amazes me is I have spent up to a 4 hours of a clinical interview. Then did psychological testing with the individual for up to 12 hours, and people still questioned my judgement/analysis of that person. Now, someone engages in one of the above acts, and people don’t even hesitate to assign a mental disorder! For most people reading this, we consider intellectual conversation the means by which to resolve problems or differences of opinion. That is our philosophical stance. We need to accept that others believe in the use of force, and killing, the way to deal with problems.
