Enforcement and investigative authorities do, of course, come under enormouspressure after each major terrorist strike to 'show results', and the electronicmedia has contributed immensely to this pressure. Twenty four hour news channelscarry shrill reports, sometime within minutes, and certainly within hours of anincident, screaming "Police in the dark", "Investigatorsclueless", etc., and officers confronted with demands for the immediateidentification of the perpetrators often feel that they have to say something.But results in any systematic investigation cannot be produced on demand. Whilepeople outside the enforcement, intelligence and investigative systems canlegitimately speculate on the identity of perpetrators on the basis of pastrecords and probabilities, these authorities must only speak on the basis ofhard evidence recovered. The police and Government agencies must learn to resistthe temptation to play to the galleries with statements on probable guilt, orwith apparent action - such as the rounding of large numbers of 'suspects' -irrespective of media or political pressures. They must, furthermore, not try togrind other axes, or to 'clean up' a 'sensitive' area under the transientpolitical and public sanction that is ordinarily extended in the aftermath of amajor terrorist strike. All resources should be committed fully to the effort ofidentifying and getting to those who are actually guilty.
