Spying on your kids -- is it OK?

[devonin]

If you never get caught then there's no harm done

So if I steal from you and don't get caught, there's no harm done? Not getting caught doing harmful things doesn't make them unharmful.

Further, if you do something morally wrong and while doing so, catch your kid doing something morally wrong, you don't exactly retain the moral highground to try and punish them.
