I figured Texas would come up in this discussion at least once. Texas has the most property protecting laws of any state in the US. A landowner or renter in Texas is allowed to use deadly force if he finds someone on his property without permission no matter what they are doing. The origin of the law comes from when Texas had so many cattle ranches and rustlers were a major problem. Ranchers were given the right to shoot people inside their fences on sight to protect their cattle. The laws have stayed on the books so there's this odd little quirk of behavior here where if you're walking through a neighborhood you always stay on the sidewalks and don't hang around looking into someone's backyard or windows as you go.
