Course noone asked for our opinions but it would seem that you did what you thought was right. From a calm -sitting at the computer stance it seems easy to point fingers with bad calls.
Blocking the path may have caused the wife or neighbor to die.
Next point is : large gahonas, gotta give you that.
I also would seriously think about a 1911, or something that is not flashy like an Ak for the in "case of future" concerns when you need to aim (accurately) and sit in the defendants seat later. Also I wouldnt think about an AK in the vehicle- overpenatration is a serious issue where innocent people could die. The shotgun is a somewhat good alternative in my opinion. Shootouts in the street are frowned on even for the police these days because innocent people hate being shot.
I do think that more people otta do something when in these situations, damn glad to hear that you was able to stop a possible murder, 911 cant do anything exept tag a body when they arent there in time. You deserve a pat on the back and a serious talk about being safe when defending others.
One atta boy
One aw shit
