Just goes to show that, as I tell people all the time, anyone can sue anyone for anything. Whether they can actually win and collect is something entirely different. But the defendant still has to go through the trouble of defending against even a crap suit.
As an aside, I agree that the homeowner should file suit against the burglar. Make it a counter-suit, and this will allow all of the evidence to hit the jury, and will allow the jury to award him damages.
