I want to agree with you, but how do you know that (I'm making the assumption here that you're not a lawyer, which may be incorrect)? This seems like the main issue - we (as in the common, non lawyery-types) don't necessarily know what things may or may not be incriminating. I'm not trying to instill a sense of fear, and I would always cooperate with law enforcement to the best of my abilities, but not at the risk of doing or saying something which could subsequently implicate me in something which is technically illegal and could get me arrested, convicted or deported.
