“You can use deadly force just to defend your property.”
Be very careful there my FRiend. Castle laws are written such that someone simply breaking in is considered a threat worthy of deadly force. It is not meant to allow people to use deadly force to protect their property.
The Castle Doctrine in Texas was successfully stress tested in court a month after it was passed in 2007. It applies to your vehicle also.
actually in Texas we still have the sundown law you can legally shoot someone just for steeling property after sundown written back in the cattle rustling days. And the Texas Castle law does say now for defense of property. There was a case in Dallas where a guy killed someone robbing his garage and he got no-billed.
