Dad, you are messed up in the head. We are lost with attitudes like that.
If you want security use the mail, hand deliver it, the phone, or just basically keep stuff in your house. Don't you get tired of volumes of law being rendered useless ( and the man hours that wet into drafting it ) because someone might get their privacy invaded.
In the "digital age" anything you put out there is public dude. Get used to it.
