"Don't steal anything you don't have normal access to."
Actually, it's in what you don't have normally access to that may be interesting for who's paying you....
Hiring people with the right knowledge is not a crime, and in states like California you can't forbid someone to go to work for a competitor (although Apple was found doing exactly that... together others) - and anyway they aren't valid abroad.
But someone with also someone else's knowledge copied is very valuable, for some companies.... especially if your own knowledge is not of that great value.
