We have a right/obligation to defend innocent life and property. But you can go overboard in worrying.... especially when you let media reports take the place of your own eyes and ears. I suggest getting fresh air, saying "hi" to the neighbors and reassessing your outlook. It pretty much comes down to the quality of your neighbors. They are one of the best things to be investing in.. That is what the Bible says, do not repay evil for evil (paraphrase) but, we can only turn our cheeks so far and so much. These people will literally kill us and our families-they don't care nor do they have any morals.
