I would agree that I think most robberies are done from within. Other than that I think people are too trusting of others. For example, I don't know why when people hang out at a bar just outside their room and someone asks them where they're staying they say, "right here" then point to the room. I never ever ever get that. They see that phat ring on your finger and "if people want something bad enough, they'll get it". I also don't understand why people wear a ton of jewelry on their vacation... WHY? ...When you meet people for the first time, they probably generally want to know everything about you- and they are probably good people with good intentions... the guy sitting just behind you may not. He's hangin on your every word.
Leave yourself to be a bit of a mystery.
