“Would you like me to arrest you?” I asked. That’s an old police trick: If you just warn people they often just ignore you, but if you ask them a question then they have to think about it. Once they start to think about the consequences they almost always calm down, unless they’re drunk of course, or stoned, or aged between fourteen and twenty-one, or Glaswegian.
