Anything you say...
...can and will be used against you.
I got an email with a great link to a blog post containing 2 links to great presentations on why you should never talk to the police, even if you're honest, or want to help, or have an alibi, or whatever. Never, ever answer any questions, no matter how trivial. Although this is an American presentation, it definetely applies to a great extend on Dutch and probably a whole lot of other European laws aswel.
Thanks to Pim for sending me this link. I really enjoyed the talk by Professor James Duane, he is a great presenter and a very articulate speaker. I'm jealous of the people in his class, it must be one good teacher.
