Deadly force can be lawful in Germany as well, reading Texas law I wonder which nuances of the laws make the biggest difference (assuming there's one).
Could also be that the difference comes from owning land works differently in Germany (because it's much more densely populated) and of course owning anything except small guns is completely forbidden.
people freqently conflate Stand Your Ground vs Duty to Retreat... with the entire rest of the debate.
I'm trying to keep this neutral, so I'm using a rather cut and dry example: Somebody kicks in your door with a pump action and starts shooting- There are _some_ jurisdictions that require you to try and flee. You kill them and they werent bodily blocking your car in? Murder charge. investigation finds a sabatoged engine? Doesn't matter.
Stand Your Ground assumes reasonableness and codifies leaveing the fight or flee decision up to the individual.
Ultimately- you're going to have PTSD either way.
