You don't want to get into the double jeopardy issue. If you want to avoid that, then you as a committee can determine that a possible criminal or civil offence has occurred and you can recommend that the House refer the matter to the appropriate authorities, which would be the police forces. You have that power, and I think that's the way it would go. I would rather not see the committee act as a court of law in this, going apart from the conclusions on the issue in hand.
