Via the Public Library of Science, Daniel Lende on the need to understand horrific mass shooting as a cultural practice with underlying meaning, rather than as anomalous, randomized insanity:
Paul Mullen, the esteemed Australian forensic psychologist, invokes cultural scripts as central to understanding why young men like James Holmes, Anders Breivik, and Jared Loughnerdo what they do. It is not because they are insane, some idea that seized them from the inside. Rather, they act out something – and the young men who do so are not random members of society, but have definable characteristics.
Mullen compares these mass killings to the Malaysian amok, a recognized “culture-bound syndrome” often defined as a “spree of killing and destruction (as in the expression “run amok”) followed by amnesia or fatigue.” (For more references, [search] Google Scholar for “amok Malaysia”.
Mullen also counters the common explanation in the United States and elsewhere that these killers must somehow be insane or mad.
