In Texas, it makes a difference whether it is day or night. I recommend reading the laws. If you shoot a theif in the day time as he's trying to leave....you are going to jail. You may ultimately beat the charge but its going to be a whipping. I'm not sure any property is worth a persons life...even a sorry one
I agree about property not being worth a life, but you never know their intent. I have no desire to take a mans life, but if you are in or around my house @ zero dark thirty then I am sure you are not there for coffee.
