Mr. Saunders, Have you thought through the implications of the argument you make? While mass murder is terrorizing, it is not terrorism. Terrorism is politically motivated and is aimed at damaging the social fabric. A whole arsenal of highly intrusive and often lightly controlled laws and practices has been developed to address terrorism. Are you suggesting that arsenal should be applied applied to all crime?  To do so would lead us much closer to the world described in Minority Report, while probably doing little to prevent the terrible crimes that you would describe as terrorism.
