However, I wouldn't want to kill anyone, much less a 13 year old, no matter how justified it is.
If he had actually "brutally murdered the poor, helpless, innocent little 13-year old"---why in Hades wouldn't he kill ALL of them, in order to get rid of any witnesses against him?!
What is moraly right and wrong can be different than what is legaly permited.
In Texas there is a huge amount of discretion to use lethal force over things no other state allows, and then some other areas that overlap with other states.
Many people use that discretion responsibly, but that is thier discretion.
So let us get one thing perfectly clear here, the man would not have been 'murdering' anyone even if he had charged in and killed them all.
Murder is defined by statute, and even running in and killing all three 'children' was legal under multiple Texas statutes if he had chosen that option.
Lethal force to simply protect property is legal in Texas in such a circumstance not just human life.
Also for those going the opposite way saying it was absolutely justified and they would have done the same in all states, this decision story is missing a key fact:
The home owner was not home at the time of the break in, he was in another nearby building. He grabbed a shotgun, and ran to the building that had been broken into, a building nobody else was located in or in any danger within. So he ran to the situation and put himself in it in defense of property. Perfectly within his rights in Texas.
They allege he beat them, for all we know that is not true, or he used force to gain compliance. A shotgun butt to the head or something similar. To a 'child' that would sure seem like a beating. It however would certainly be justified, and considering he could have used lethal force anyways...
So in the state of Texas the man decided to defend his property, grabbed a shotgun, and then headed into the danger and the building he was not in to put a stop to it. In the one and only state of Texas he could legaly have ran right in and used lethal force on all of them and it would have been legal and not murder even with no threat or danger posed to himself. So self defense justification would not even been necessary in that one and only state in this circumstance.
In all other states in the nation grabbing a weapon and running to a building nobody else is in any danger in, and using lethal force outside of self defense it would be murder. Not in Texas.
Further that is not what he did. He did eventualy use lethal force in self defense, a criteria that was not even necessary at the start.
So this is not some man that was defending the home he was in when intruders broke in. This is a man that grabbed a weapon and ran to defend property in another building, something perfectly within his rights in the state of Texas. Any person in most states has the right to stop such a crime (but a court might flay them alive for it later), but only in Texas is lethal force justified in such a situation, at night, in defense of only property and no lives. In most states if a person did that and then a shooting resulted they would be in a serious argument for thier life in court as to whether they ran there to shoot or self defense was later required. In some states with a duty to retreat they would already be guilty regardless of that argument. Texas is completely different, lethal force was already justified even if no threat was present, and even if the owner sought out the individuals before using such force. What would be murder in most other states was already legal in that situation.So even if it was not in self defense it could have been legal, but it WAS in self defense. So that is why it should have been no billed in Texas whether it was self defense or not, and the issue should not have even ended up in court under Texas law.
So people need to remember every state has different criteria for lethal force, and the only state that allows lethal force in defense of property in certain situations is Texas. So while what eventualy happened may have been justified in a number of states, many other options would have also been justified only in Texas.
So whether you or I agree or disagree with any part of Texas law, it is Texas law, and situations in Texas need to be viewed under context of Texas law.
So most states allow self defense to prevent serious injury or death. Some others require no retreat if possible, and allow defense of a dwelling with the presumption of self defense. Others allow it to stop certain felonies.
Only Texas allows someone to seek out and advance on a criminal to defend property with lethal force when no lives are in danger and certain criteria are met, or to even shoot fleeing criminals to stop them from getting away with property after they commited certain crimes. As discussed in the famous recent incident of Bill Horn (which is argued self defense, but was legal even if it was not.)
