  • I came across this in the local press:

    "A man was arrested in the city centre for being drunk and incapable at the weekend."

    I asked a local Bobby what this actually meant. "Well, drunk means drunk," he said. I presume this is not a crime, otherwise you would have to arrest Scotland. "Incapable means he couldn't stand up by himself. In these cases we call it in, they're picked up and sent to the shelter."
