[Russ]

On the basis we know next to nothing about this case, from the little we do know I'd say he may have a good chance of getting off this, or at leave getting off a murder charge.

He was attacked/burgled by 2 people which generally speaking usually means a weapon can be justified as self defence. As long as they hadn't agreed to leave the property and he stabbed them repeatedly on their way out or something daft like that they I can see this going his way.
