I take your meaning but all one has to do is do a search on it and you'll see how things can go awry. I'm all for defending your home but everyone should familiarize themselves with just what the law will or won't do for you where you live.
If I'm home and somebody breaks in I'm not going to bother asking them why.
But when it comes to theft, an old article from (of all places) the NRA advised not to take deadly action as it can come around and bite you in the ass. Sanity made sense back in the day.
Attitudes have changed since then as has the leadership of the NRA but I'm in no big hurry to put someone in the ground. As far back as I can remember, experts have always recommended a dog and if you must, a shotgun.
All the best,
