People call me crazy when I go out to check on a noise armed, but you just never know. Its a shame this happened, but it should remind us all about the problems out there. I think, however, that if there is a noise and your unsure its one thing. If you know its a prowler, stay armed and ready to go check, but also get the cavalry on the way. I know that the cavalry does not show up fast in some areas, but it does not hurt to get them over there with you. You never know when its not just a prowler, but prowlers. Safety in numbers so to speak. As long as the cops know your not the prowler and don't shoot you.
