I think we're missing some key details into the incident. It does sound a little outrageous that he is being charged with second degree murder. It is my understanding (and I'm not 100% sure about this) that under our laws, you have a duty to retreat from violence and that we don't have a so-called Castle Law like in the US. So, this means the expectation is to run away if you can.
Now, the fact that he had a firearm and killed the intruder....who may have had a firearms....is bizarre. Especially since he had a legal and registered gun...But, the other question here...and i don't mean to blame the victim of a home invasion....but why was this house targeted? Is this Ali Mian doing illegal shit, like selling drugs or guns? Is he known to police?
This story reminds me of something that happened in Lethbridge (I think) about a decade ago. Someone tried to break into a home, the owner scared them away, and took a shot at them with a rifle as they were running away. Didn't hit them. However, he was outraged that he was being charged for a firearms violation. Again, under Canadian law, you don't have the right to kill people when they are not threatening you or someone else....
