I wasn't presenting it as a justification, just explaining how I read the law.I'm not comfortable with this as a justification for the use of deadly force.
Also pointing out that the law itself contains nothing that might be interpreted as valuing human life in terms of property or vice-versa.
Of course it could--assuming that the public and the representatives of the public/legislators felt that was reasonable. Just as the public and the legislators believe that it is reasonable to allow people to use deadly force to protect life in many places and have passed laws reflecting that belief.It seems to me that if it's a valid argument in the case of property crime, it could also be used to justify the use of deadly force to prevent or stop all sorts of other crimes: drunk driving, indecent exposure, or littering, for example.
That's a pretty oversimplified version of the law.It's not clear to me that "But it's mine!" is a sufficient reason to put a petty theft in a different category from these.
As I mentioned earlier, if one reads the law, it is fairly obvious that deadly force is allowed under circumstances where there is little to no chance that the law would be able to recover the property--in other words, under circumstances engineered by the thief/robber/burglar to make identification/apprehension/prosecution nearly impossible. The law simply allows the property owner to do what he can in a situation where the law is impotent to provide redress.
So, for example, if a thief doesn't want to be legally shot in TX for theft, he can commit theft in the daytime. It's illegal to use deadly force for simple theft in the daytime because the assumption is that if the property owner is close enough to use deadly force in the daytime he is able to see the thief and therefore the chance of being able to identify the thief to the authorities is sufficient for the law to take control of the situation. Under those circumstances the property owner can't use deadly force--he has to report the crime, tell law enforcement what he saw and what happened and then let the government deal with the crime.
If one wants to attempt to justify this law, the place to start is with that theme--the idea that the government will not tie the hands of a property owner to recover his property in a situation where the circumstances make it essentially impossible for the government to deal with the problem.
The law clearly isn't about ruling on the relative value of life vs property; it's based on the idea that if the government can't help, it steps back and allows the property owner to do what he can to resolve the situation.
