In Texas you have the right to persue the thief to recover property. The use of deadly force can be used if any other force or action would put the victim in danger. Since these kide were being chased by the victim and they refused to stop, the car chase was puting both parties plus the public in danger. It could be argued the victim had no other recourse, tht is, here in Texas. Hell, the store owner would not even had been arrested down here.
