Absolutely. You couldn't allow the public to be at risk, for example, with someone rampaging. They'd need to be contained, clearly, but could you establish a secure perimeter? In other words, if the individual is harming himself or herself--mostly himself--if that happens, then you've got to move in. Could you do that? Yes, I think you could do that in some circumstances, but there are going to be situations where that will not be possible.
