Reliable proof of all such things is pretty much limited to one's own direct experience.

Having had a wee bit of direct experience myself, I have all the proof I need.

And that's the way it works for most people....although there are a good many people who will believe anything at all if CCN or somebody like that on the TV says it's true... ;-)

They are the "daddy knows best" type, I guess. I don't see it that way, not having ever had much trust in Big Brother.
