Based on clinical experience of killers. Includes a selection of USA/UK serial killer studies. Exposes police and other failings and shortcomings and the perversity of 'defences', 'excuses', etc. Strongly critical of USA gun laws and attitudes or perspectives making for an unhealthy environment, moral vacuum and lack of official/individual awareness and responsibility.

Dr Eric Cullen describes how he was 'so profoundly moved' by his inescapable conclusions about how serial killers are 'made' that he felt compelled to set out his findings. A critic of the serial killer growth industry, unhealthy interest and ill-informed comment he sets the record straight. Serial killers are made not born.

But his more central polemic is that serial killers are one of several malign human by-products of a dysfunctional, unduly permissive society, overwhelmingly American, brought about by modern-day culture and lax moral standards (as also reflected in other countries to the extent that they pursue a comparable way of life).
