Hi DBII,
>In Texas, one can use deadly force to protect personal property even when you are not the property owner.
Oh well, you can - legally - do that in Germany too. However, here you have to observe the principle of proportionality, meaning that the force you exert has to be limited with a view on the damage that is done by the people you are defending against.
The level of potential damage that justifies the use of lethal force is seen as fairly high by the German jurisdiction. I'd expect that Texan to be found as having exceeded the legal restrictions if he'd be judged by German law.
In fact, if my impression is correct that he announced "I'll kill them!" unconditionally to the operator (I might be wrong), I think might even be a chance that he'd be charged with (or sentenced for) murder instead of man slaughter as it could be concluded that he planned to use lethal force regardless of its requirement.
Not that I'm an expert ... and of course, I don't have a clear picture what happened that night.
Regards,
Henning (HoHun)
