The issue that has been raised often concerns subjective and objective criteria. You actually spoke to some of the considerations nicely. You also talked about reasonableness, as far as the person's perception goes. Would it not be worthwhile to specify that it is a matter of the person's own perception? In different circumstances, we would be talking about reasonableness in the sense that a reasonable person is involved. As you said,
it's in the heat of the moment. It's very hard to put an objective person in those circumstances.
