Nope. This is bad advice. Those are the sorts of answers you give in a deposition or on the stand, after going over the case with your lawyer. However, if you say those things to the police, then it can and will be used against you in a trial. Have a totally legitimate alibi? Well, if you told the police that you “don’t recall,” then they’re going to use that as evidence against you in the trial.
@Zuzak@hexbear.net has the magic words you are supposed to use. If you don’t “invoke” your fifth amendment right or ask for a lawyer, then the police can continue questioning you for as long as you keep giving nonanswers, or as long as you stay silent. You need to say the magic words for them to actually stop questioning you.
Yes, this system is fucking insane. Staying silent is different from invoking your fifth amendment right to silence.
