Don't let the fox guard the henhouse.

Don't assign the duty of protecting or controlling valuable information or resources to someone who is likely to exploit that opportunity. You're going to put your ex-convict brother-in-law in charge of your business? I can't tell you how to run your company, but don't let the fox guard the henhouse.
