The Fifth Amendment to the United States Constitution prohibits the government from making you answer any questions that may incriminate you.

Refusing to answer questions is NOT obstruction. Lying to the police is obstruction. If you say "I don't know" when you really do, that's obstruction. I suggest using the phrase "I'm sorry, but I don't believe it is in my best interest to answer your questions".
