I sold some frags to a guy quite awhile ago, he was one of the nicest guys I've met in the hobby. A few years later I see him on the news for breaking into houses and hiding in the basements stalking numerous people and theft.
first off people change, and not always for the better as you saw. I have heard some of you are armed, some of you check out people, some of you protect your solitude. There is no right or wrong. Just wrong people at times in wrong places. We all have to do what we feel comfortable doing. Live your life and stay safe. I have 17 years in law enforcement and know the risks out there. I have never let someone into my home that have not been referred to me by a mutual friend of that I have not met on here and researched first. Remember a person wishing to harm you will have the benefit of surprise.
