Reading this thread makes me feel a sense of fear, but also relief; a stalker who trespasses is not to be taken lightly at all, and it can only escalate from that point. I do believe that's a point of no return. The relief comes from what I am reading from other posters. I know that we have many conservatives, and many liberals on board here, but it's become a glaring truth that when confronted with true danger, you guys will all do anything to protect your loved ones. Maybe there is hope for the world yet.
Joel, you take care of this, and take care of it quick. I don't even know you or your sister and I am concerned for both of you. I have to tell you, if he's established a pattern and you know he will be back tonight, tomorrow night, etc etc, I would not hesitate to camp out in a place where I could get a good view and sneak up on the guy, or pick him off if he's brave enough to attempt unlawful entry again.
Good luck, and I hope everything comes out alright.
