Lets see... pictures were taken of some jagoff's house. Thats legal. He was delivered, not using a post box, a goatse envelope. Thats also legal. He called and threatened Col, which I believe is a serious misdemeanor and carries a stiff fine.
Col, you damn sure better let us know about pressing any charges. I think, in terms of an internet war, putting him in jail for a few months and getting fined a few grand would translate to strategic nuclear weapons. Or a face-plant finishing move with some english on it.
