I missed understood your first post when you used the word "escape" I thought you meant, if the home owner had a means to retreat from the threat and escape then they could not shoot.
Apparently you meant if the intruder was making an escape, that is withdrawal, you can not shoot. Sorry for the misunderstanding. That is the same here in the US and especially in Arizona. You can defend yourself against an attack, however if the attacker is retreating, leaving and no longer on the attack, in general we can not use lethal force to stop them (although there are special circumstances which would provide for this).
Sorry for the misinterpretation of your original words.
