Legaly, property and life are not interchangeable or equal
Haven't looked into the Texas general laws on 'deadly force' as of late, except its been in the local newspaper to crack down on Cops shooting on fleeing vehicles. Seems all that's needed is a witness or two (usually other cops) to say the vehicle was trying to run down the cop (trying to flee) so he feared for his life and started firing at the vehicle with 'deadly force'.
It used to be, and probably still is that 'deadly force' can only be used if great bodily harm is imminent, and/or fear for own or others immediate life. In other words, just a trespasser in your home or property cannot be shot. If Grandma shot at a potential burglar/rapist through the window while attempting to enter, then Grandma needs to go outside and ensure a hole through the screen or window to show forcible attempt to enter. Leaving a door unlocked and a trespasser is in your home is not just a reason to shoot.
Shooting a thief or burglar is not justified 'deadly force' unless fear of imminent life/rape from the said thief or burglar. HOWEVER (I believe it is still on the books) shooting a thief at NIGHTTIME can be justified if there is no other way to recover the items(s) being stolen. The 'other way to recover' usually has to be argued in court. I recall reading in the local newspaper around 15 years ago where a local business man woke up in the middle of the night with a trespasser in his bedroom. He grabbed his .357 Mag as the guy was fleeing the bedroom , chasing him firing his .357 as guy was going out the back door, hitting him in the back where he died on his rear lawn. The business man was not arrested, nor did the Grand Jury indict, as the man's wallet containing cash was found in the trespassers hand, it happened at NIGHT, and there was no other way to 'recover' the item (money). I always wondered if the Cops, thankful that this burglar was finally stopped, hinted to the business man...where is your wallet?
Hope we get more new teeth in our laws, like some other states recently revising their laws, to allow more justified shooting of the bad guys.
