Texas, I love you! Poor man, hope the jury is reasonable.
In Texas, shooting and killing someone though your door would also get you a murder charge.
Even in Texas, the anecdote is if you shoot them breaking in through a window, you better drag them all the way in the window. The bottom line is you need to convince the powers that be that you were in fear for your safety/life. Loud in the back yard may be a hard sell.
