You may be right about the statements not always being the case. The point may be should have been that official sources just cannot be trusted to provide you either with accurate information or good advice.

That does not mean they will never give out accurate information or good advice, only that it can never really be trusted to be either.

However, just to make a point. The nitwit in charge of the NATO riot in Chicago that is about to happen recently suggested people should bring their children down to the lake front for a picnic during the riot.

This is while the city as part of its security precautions for the event is shutting down the museums along the lake front and the entire harbor.
