http://en.wikipedia.org/wiki/DesecrationDesecration is the act of depriving something of its sacred character, or the disrespectful or contemptuous treatment of that which is held to be sacred or holy by a group or individual.
The tea bagging is not just unnecessary & rude but such a waste of perfectly good tea bagging.
I would think a desecration would have to be physically damaging to be actionable and by the article "the judge refused to sign a warrant on them" probably the law thinks that too.
I certainly intend to piss on the grave of my xcousin should that utter douchebag predecease me. Well worth risking a $500 fine. I should at least have some satisfaction out of the 50 years of good work I put into that relationship.
Why do we bother to bury our dead if not to be able to continue to express ourselves.
The trespassing charge is interesting, but again, I think you can fight that. We've been dancing on the graves of others probably for 1000s of years. Cemeteries are left open for people to come by and express themselves. You can visit without a personal invite the grave of Malcolm X or the crypt of Judy Garland http://www.ferncliffcemetery.com/about/celebrities.php
If it is not trespass to visit a grave to express ourselves, then how is that expression limited? Someone might visit to express grief and cry, or remember happy times and laugh, or they might express anger and dance.
