The burglars in prison carry on 'burgling'. One young chap I was visiting at The Mount Prison in Hertfordshire emerged from the prisoners' door in tears, because 'someone had stolen his bag of sugar'. I'm afraid I flippantly replied that amazingly there was obviously a thief in the building! The man was serving a four year sentence for... burglary, but he couldn't see things from a victim's point of view. After the visit I told one of the officers, and we had a good laugh. Apparently, everything in there goes missing, they're at it all the time.
