Grooming Security Business

After 9/11 there has been an unsecured environment in all over Pakistan due to War against terrorism. In early 1990's we can see just few security agencies in Pakistan which were also not known to many. But after 2000 we can see that security business is grooming and becoming just like an industry. Environment has so much changed that now we usually see a Security camera and barbed wire on walls of houses and offices.According to an estimate there are about 600 security companies working in Pakistan. It's a Question mark against our security agencies that why this business is grooming so much. Does it shows their poor performance or something else???
