So you don't think that sexual activity involving underaged children, with or without the consent of the parents, is a matter of public interest? Jacko claims the kids he goes to bed with are there with their parents' knowledge and permission. So that's all right, is it?
I don't tell people how to raise their kids... it's none of my business.
I do tell people (through my representatives) how to raise their kids. I tell them they can't injure them, starve them or sexually molest them. I tell them they have to send them to school. Etc.
Illegal interception of oral communications, on the other hand, IS a matter of public interest.
It varies from state to state. In this state, for example, it's entirely legal to tape a meeting at which one is present.
