As an electrician, this kind of story scares me. I need to do more research, but I can't figure what they thought they would get from electricians. The truck, tools, or perhaps credit cards? It just seems a lot of work to only get someone's credit cards, but it's not a bad idea when used the right way (and you suspend legalities).
This is exactly why I carry at least until the point I have to go into the crawl space or attic. The last thing I want to do is lose my firearm in the insulation (by the way, I once lost my keys off a carabiner after my belt loop broke without me knowing it) and have to go back with a magnet.
I have to admit there have been times where I've carried into someone's house and thought about how they might have felt about me if they knew I carried. And then considered putting my firearm back into the truck. These are the stories that strengthen my resolve. Please consider this event if you hesitate in exercising your 2nd Amendment.
