@Alex_Linder people say self-defence when clearly it was cold blooded murder.
1. A person climbing through a barricaded door is in no way or capacity to in any reasonable method even threaten the alleged defender.
2. No weaponry was found on her. Hostile intent must be proven beyond a reasonable doubt
3. Government institutions are not covered by self-defence laws in any way like citizens are. Self defence an exclusive right for the citizen against domestic hostiles. Never for the State. The State is there for foreign hostiles.
