Re: The law is wrong
Changing the law in the way you suggest may have unintended consequences, e.g. making anyone who grabs a kitchen knife off their own kitchen counter defend themselves from a burglar a murderer, without any wiggle room to argue self defence. The law is already pretty strict on that; the act of opening a drawer to retrieve a knife, rather than it being on a counter, makes it far less likely that a plea of self defence will be accepted. Same goes for stabbing someone if they're not actually facing you.
