The worst criminals ever are the ones who record their crimes on their mobile phone cameras and distribute them to their friends.

Seriously.

How smurfing retarded can you get?

I usually find myself more dismayed that someone could be stupid enough to categorize their crime with hard evidence than the crimes they actually commit.

I will presume, however, that you do not mean worst in the sense of most incompetent, but rather in terms of most evil/prolific.

Let me tell you; it's not some nutjob cannibal.
