A couple of years ago, when we were burgled, the police ran down the culprit. They found his fingerprints on an inside window pane. They obtained CCTV footage of him buying bottles of booze from a convenience store with my debit card. They found him with stolen goods in his possession. He was, to put it mildly, a notorious habituable offender. And he was caught red-handed. Bang to rights. An open and closed case. Beyond any reasonable doubt.
