He found an easily movable good (silver stemware), located in an reasonably accessible part of most every house (downstairs, usually in the dining room), using a crime whose punishment has lessened in severity b/c of its decline in perpetrators (cat burglary) & that he had mastered (stayed in great shape, was meticulous, taunted cops, etc).

Kind of hacked the system if you ask me. Of course he still got caught...
