Depending upon the criminal laws of the State of California, purposeful exposure of one's buttock's on a landlord's surveillance camera could be crime, for example indecent exposure depending upon the degree and amount of what was seen on the surveillance camera.At best, the tenant's exposure of his buttocks on the surveillance camaera was in poor taste. A civil action for the conduct only seen on video camera would not seem to be worthwhile legally.Whether law enforcement would be willing to file charges against the person who made the display seems unlikely in that there was no significant crime committed. The costs for such prosecution, even if considered, would not be warranted under this California's budgetary crisis.Good question.
