Yeah. That's nonsense. He took pictures that the ids put online and he....put them online? What are they suing for? Copyright infringement?Screw them, make them all pay.
While I certainly would not be agreeable to paying any of his damages if my kid did not damage anything, going after him is complete buffoonery.
I'd like to think that if my kid DID take part in the damage, that I would be willing to pony up for it...and beat his ass. Of course, I'd also like to think my kid would not ever do such a thing.
