Terrorist organisation as well as governments sometimes employ this weapon to eliminate political opponents. All this reinforces the need to evolve a comprehensive theory of security, a mental framework to analyse and counter threats to political personalities. A popular misconception noticed both among laymen and pro fessionals is that security has to be foolproof and failproof. They are only deviding themselves with an ineffect illusion till the disaster occurs when they start looking for scapegoats and call at a security lapse. Security is never absolute, it only provides for deterrence against risks.
Deterrence is achieved by increasing the costs to the agency posing the risk.
Security is all about countering the risk. From which quarter, at what point in time and in which place as also for what reason, the risk is arising should not be a matter for conjecture and chance. It has to be forecast, pre dicted on a rational and scientific basis. A multiple of factor X may pose a threat to the protectee. Even if n is o, the minimum assumption in any security exercise regardless of the stature or nature of threat to the protect is that IX atleast is present.
