This is the same thing law enforcement does on a daily basis, they patrol the streets and protect the citizens, we patrol the electronic highways and we protect our clients. I come from law enforcement, and this is no different than investigating computer crime and it shows you that even though they re using computers, they are still not sophisticated.
Criminals are criminals.
People that do bad things do them for the same reasons. The number one reason is greed or revenge. The motivation to commit these acts has not changed, only the tools to commit them with. You not only have to be a good cop, you have to be a good technical investigator. You have to have both sides of the fence, the cop and the techie.
