Let's say that you tell the officer: "The baby ran off with the bear that way." According to this case, you have now waved your 5th amendment rights. Now let's say, instead of running after the bear, the officer asks you "where did you hide the baby?"

Now, if you're smart, you would keep your mouth shut. You're innocent and anything you say can and will be used against you, in the event that the officer doesn't or refuses to believe you. But, according to this case, if you do keep your mouth shut then the officer can now offer as evidence to the court the fact that once he asked you specifically about the location of the baby, you didn't answer.

The prosecutor will then, legally, stand before a jury begging the question "why didn't he just answer the question? Obviously because he is guilty." Now you're the guy last seen with a missing baby who refused to say where the baby was. You're obviously guilty.

I, for one, will never speak to another on duty officer again except to the extent required by law.
