I think she was right to have shot the burgler. Unfortunatly, he can sue her for shooting him, retarded as it is its true. I don't really support this kind of nonsense.
So sue him back. The answer to these ridiculous law suits is to file an equally ridiculous countersuit. Better than that, file ten. Sue the burglar for invading her house, for emotional trauma, for shooting Kennedy etc. Any judge stupid enough to believe that the burglars case has merit would probably sign off on the countersuit too.
Any judge not stupid enough would probably sign off too just to teach the burglar a lesson for bringing such a stupid case in the first place.
Once people realise that bringing a stupid case means that you lose and end having to pay out for it people will stop bringing them.
