The main problem with the notion of self-defense is it imposes on justice, for everyone has the right for a fair trial. Therefore, using a firearm to defend oneself is not legal because if the attacker is killed, he or she is devoid of his or her rights.
Unless you have crap for brains there is no problem here. The right of self-defense trumps the right to a fair trial. Another way to look at it is that the perpetrator gave up their right to fair trial for the duration of the violent attack.
