Why does this reminds me of that "Don't talk, take action" quotes. One of the Police said to me, "instead of threatening to shoot someone, just shoot them to kill, then drag the carcass inside your house". That was back oh gosh back in the 90's in New Mexico. The reason for that is the offending person that you're threatening can get you for well threatening them or harassment even on your own property, can file legal action against you, where if you were to kill them, they cannot do a thing about it and since dragging them inside of your own house affords you to classify as self-defense. I don't know if this is true or not, or is still true to this day. So what it appears to come down to today or in the future is, don't make threats, just act on them. It might get to the point to where it is better to commit a crime then actually make such threat... or keep to yourself.
