Careful with this advice. At least up here in Canada, and as far as I am aware in England as well, there are a few situations where "telling them nothing" can create more problems.
One that comes to mind is in regard to a possession of stolen property allegation. If you acquire property innocently, and it turns out to have been stolen, an unwillingness to communicate can really hurt your ability to later argue a "good faith acquisition" defence.
Alibi defences are another example.
Maybe that flies in Canada, but here "anything you say can and will be used against you". Much better to shut the hell up, and if arrested let a lawyer speak for you. The most successful defenses here rely on the accused never having said a damned thing. The first thing a layer here will ask you is "what did you tell them?". If you say "nothing" he'll say "good boy". There is even a card you can get here that says 1: your name and address, and 2: I'm not telling you a damned thing.
If you have an alibi defense, that would assume there has been probable cause to arrest you in the first place. Your alibi will come out in court. It will do you no good with the police as far as arresting you in the first place, and you could quite possibly bugger it up by saying the wrong thing.
True. The nearest municipal police are in a town of 9000, ten miles away. The sheriff's department has 538 sq. miles to patrol. I have no connection with either, and rarely see them. Only a few area residents may have adversarial relations with area law enforcement. I consider that to usually be more of a deficiency in those individuals than in law enforcement. Here in the boondocks we may not have big city advantages, but life is good.
