My take:
The only weapon I usually carry with me is a pocket-knife. I never carry anything of value, and am always aware of my surroundings. I would only ever use it if I truly thought I was in danger.
Now at home, I have a (large) variety of guns, from hunting rifles, to muskets, shotguns, and handguns. I regularly shoot on my own land, and hunt with them. Again, the only time I would use them is if I felt me or my family was in danger.
After the robbery at my house I have installed an advance alarm system, and an extensive CCTV system.
I have a question for those of you who know the law better:
Around my property, (~6 acres of woods), I have no-trespassing signs all around.
Does this mean that I can legally shoot anyone who walks on? Do I have to warn them first?
Obviously, I would never just do that, but I have been wondering about this for a while.
