"So if you found a bong and a pack of rubbers in your 16 year old daughters car you would draw no conclusions or persue a path to find the extent of the situation?"

Those items are forbidden in my home, therefore their existance would indicate guilt, regardless of the "extent of the situation".

While their non-existance doesn't necessarily prove innocence, it certainly should award her with some reasonable level of trust, however guarded.

We haven't found anything, therefore there are no conclusions to be made except those based on speculation. Thanks for making my point.

This is a really old topic, one that will never be resolved here. Please feel free to respond if you like, but I've said what I needed to say and won't comment again.
