Botnet C&Cs are not naturally occuring phenomena.  Relying only on 
defensive security, and not arresting the criminals, will just result
in the criminals becoming bolder and more aggressive.

In most cases ISPs are just taking action against innocent bystanders that 
got hit in the cross-fire. Those bystanders aren't the cause. If you let 
the criminals continue trying over and over again, you are just training 
them to become better shots.  Telling your customers they should wear
bullet-proof vests whenever they go outside isn't going to stop snippers.
Arresting the snipper is going to stop the snipper.
