Laws are ambiguous to say the least relating to who you are and your profession, you make a mistake and your marked forever, with that being said and my background in the law profession I'd counsel you to get a big dog to protect your home, people don't realize the ramifications both short and long term once that firearm goes bang. I've seen professionals come b4 me with tears n their eyes knowning their life and assets with never be the same because they over reacted to a situation, better make sure it's a life and death situation and you can prove it without a shadow of a doubt. I tell people if you can RUN !! If not you and the perp have a serious problem ....good luck n your quest for protection but don't stimulate a situation that can be resolved with conversation ....
