I guess it might be no different than them asking "were you at X on the night of Y", which obviously you don't have to (nor should you) answer.
However you ARE required to answer their questions if they are not interrogating you as a suspect... I wonder if asking if you have weapons could possibly be construed as just a safety question and not being questioned as a suspect.
