I don't support vigilante "justice" or revenge.
But when it comes to a violent home invasion, I'm going to cut the victims the largest benefit of the doubt possible for "heat of the moment", fears for the well being of others, etc, if they end up using violence against the violent criminal.
I think a 30 minute high speed car chase would be out of bounds.
Chasing the invader as he runs into a back yard, or down the street for a hundred yards? Whatever the legal technicality is, I'm going to give benefit of the doubt to the greatest degree possible.
Note, this applies to a violent home invasion. It doesn't apply to kids stealing a lawn ornament or TPing a yard.
A non-violent home burglar caught in the act who flees falls somewhere in between these cases.
