In many states, laws require there be a warning, either by a sign or warning by the property owner, that you aren’t allowed to be on property before you can be convicted for trespassing on the property.
In Texas as in Georgia signs are needed for exterior property. Texas has the purple fence post law which covers trespassing of exterior property. Structures in the other hand with doors regardless of there construction status automatically are considered unlawful entry and burglary of a structure both are state jail felonies and neither require the actual taking of property to be a felony. The fact that the door or window was breached alone make it a felony. By having a barrier that must be breached it is legally implied that access is restricted and by crossing that barrier a crime has been committed unless authorised or invited by the owner or owners agent of said property. Texas also has a fleeing felon clause and force including deadly force is authorised to stop a fleeing felon in most cases. The Georgia statue was put in this article it seems they also have a fleeing felon clause. If this guy was fleeing a burglary and tried to grab the shotgun and got dusted for it then a not guilty would be my vote jerk give these two guys a medal for taking out the trash. Of course he was an aspiring rapper living with momma and he dindu nuffin enjoy your dirtnap scumbag.
