Not true. You are allowed the use of 'force' in self defense. Here in the great state of Tejas you are allowed to shoot burglars should they enter your dweling ...
See there in lies the problem, I live in the peoples cooperative of New York where the perp's position and direction when shot, stabbed etc. are important. Texas seems to protect the honest citizen much better.
NYS has nothing to offer and if I did not have to consider moving my pipe organ (a musical albatross if there ever was one), I'd be heading to a state that allows me to protect my family and as a side benefit may actually have EE jobs available.
