To my mind it should be the case that, if you commit a crime and your victim (Or those around him/her) turn on you. One of the legal rights that you should lose is the right to self defense.
If you injure or kill anybody trying to escape, even if you are in fear for your life, you should not be permitted to use "Self Defense" as a defense.
Indeed, I would regard any such outcome as Felony Assault/GBH/Murder with appropriate sentences to follow in addition to those imposed for the original offense.
It should be made quite clear that this is one of the risks that one takes should one choose to commit a crime in the first place.
Ok so you stole a loaf of bread, some wierdo has seen it and approaches you with a knucle duster, he begins bludgeoning your head in and it's totally fine because you can no longer defend yourself from being killed?
This sort of ****** argument bores me, can you atleast attempt to stipulate exceptions?
