OK, who dunnit???
It is time to fess up, I don't think this was a Joker strike because there is no note and that is his MO. I will post pics when I find my camera in the rubble! Unprovoked attacks can lead to retallitory strikes. BTW, very clever but I am not buying the name on the return address(which is phony). I am certain there is no one here named B.ork. Very funny, now own up to the carnage!
