I think that's a fundamental point which will be a sticking point for us. I do believe all life to be equal. And I wouldn't say it's an absurd extreme to suggest that although I won't risk my life over that of an assailant, I do believe I have a duty to that person to not jump straight into killing them because they broke into a shop.

You're right it's not justice to treat the victim and assailant equally. But the punishment does need to fit the crime. Breaking and entering and looting are not proportional to getting shot.
