But then you have a case where the officer will try and use what you said against you. So, even if it wasn’t knowingly in truth, in practice it will be up to you to defend that truth. Whereas silence saves you the hassle.
In practice, good-faith and respectful interactions with law enforcement have a positive outcome.
unfortunately the positive outcome they often have is teaching people that is a very bad idea to have goid-faith interactions with last enforcement.
In practice paying a lawyer $250/hour to sit with you while you answer questions (or not answer) is cheaper than missing out on five years of income and all of the other consequences that come with going to prison.
Somehow, I doubt you have much "practicing" this.
Good faith and respect in interactions with law enforcement only seems to go one way, though.
