Gankers, or most players for that matter, who would risk loosing a full cost rebuy, would not stay long enough to let their ship get destroyed, they would pull the network cable or do something else that cause the same effect.

fixed bad wording
What ever. It makes sense and it suits the situation for the PF to just disavow them. Even just so the PF can save some credits that they are currently paying on the criminal's account.
Deterring gankers, for real, isn't even necessary, or my point. Putting them in a situation just forces their hands, you know, letting them show their true colors. It's the best thing for them.
