Hackers like that though are more costly and harder to gather evidence against. I really think police now do cost benefit (At least in the us), before deciding if there going to do much in investigation. Then if they think there is external political, government, other large corporate involved, I would think they would cave. Some case with digital, they just find multiple traces and just give up... People forget that yeah leaving little or no evidence is great, but to stop or complicate the ability to convict, one can also intentionally contaminate a scene, or even overload it with garbage before and after. Conflicting statements, and a party can be great (As a metaphor)!!
