Worldwide private security organizations, ranging from unarmed security guards to "combat-capable" paramilitary groups, can act as a force multiplier to enhance security. A critical component of official and nonofficial security regimes is the role of government oversight in ensuring criminals and terrorists are unable to hijack private security organizations for their own objectives. A major problem is the ability of governments to manage or oversee these security elements, which varies significantly from country to country and region to region. In many countries, government control is almost nonexistent, creating an environment in which private security organizations are ripe for criminal or terrorist manipulation.
