Schneier on Security

There is one rarely used avenue for checking trustworthiness: fully investigating everything on the person's resume, work history, and educational history.

I would not trust HR people to do this because their own backgrounds are almost certainly 'storified', to put it kindly.

People trust safe deposit boxes because opening one takes five-way joint cooperation -- your key, the bank's key, the person who opens the vault, the timer that allows the vault to open, and whoever opens the bank in the morning.
