I hate the suggestion to leave some money in an obvious place for the burglar, like tax for nuisance idiots. It isn't like some kind of professionalism is going to keep them from tearing up the place anyway they obviously don't give a shit.If the goal is to get in, get something of value, and get out, then quite possibly. My car was once broken into and they took a blanket and some cheap sunglasses that were visible, leaving about $30 in change in the door storage and ash tray. Although, obviously value is in the eye of the beholder, Chicago winters are pretty cold, so the blanket maybe had more value, and was easier to carry, than cash.
Would you leave some easy to access credit card numbers out on your server to keep them from going after the rest?
Quite possibly; this is called a honeypot, and is often used as a early warning system and a way to keep intruders busy with the not-obviously-not-valuable stuff while you monitor them and track them down.
