Let me get this straight:
You can't carry a lock blade knife like a Leatherman Wave in Austin (from the post on swords & RKBA)...
...but you can shoot a kid in the back who's stealing chickens?
Seems a little inconsistent to me.
Deadly force should only be lawful in response to violence or threat of violence (including the implied threat of violence inherent in kidnapping, robbery, burglary and arson).
Property crimes call for restitution. Killing someone for stealing violates the principal of "an eye for an eye" and can't logically be considered self-defense.
