Re:worry.. (Score 1)

what are u talking about? of course it is impossible to detect all of them..detecting criminal takes month or even years for big crime. Much worse if he is one of an important or high influential guy to the society. But techniques such as data mining and AI systems may help investigation to be easier. p/s: Im much worried if my credit card was fraud and there is no way to stop the fraud..what a lousy technology if that situation happened.
