Another thing 'we' here in the EU don't really get; if you watched even ONE cop show from the US, you know that you ONLY utter ONE thing when you get arrested/detained/whatever: 'lawyer'. And nothing else. So why, in the same cop shows and real life, do people start blabbing?
In cop shows, because it serves the plot better; in real life, because humans are not very rational creatures and the intuitive need to try to explain yourself is strong, especially if you're in the company of people who know a couple of psychological tricks on how to make people talk.
