I know plenty of people who leave nothing of value in their cars, and leave the doors unlocked. They would rather lose the .69$ cents in their ashtray than have to pay who knows how much for a new window when all that was in there to be stolen was .69 cent$.^^^^Yes, this^^^^
If you slow them down enough then you can introduce them to your "Little friend"
There was a great show that doesn't seem to be on any longer called "It Takes A Thief". Basically it was 2 ex-thieves that would break into peoples houses, rob them blind, and then tell them what stupid things the home owners were doing wrong. Most of the time they gained entry because a door or window was left unlocked or the homeowner had the ever-so-original idea of leaving a key under the mat. They would also leave all kinds of valuables/personal information/CCs on the kitchen counter for anyone to take or walk off with. It was really a good show and gave a lot of information. One of the main points of the show was deterring and slowing the thief down. The longer it takes someone to break into your house, the greater their chance of getting caught. The longer it takes, the greater chance of them giving up.
Most people don't think to take pictures of every room in their house, record serial numbers of appliances, TVs, computers, guns, EVERYTHING, and keep them locked in a safe place with all unused CCs, check books, CC apps, etc (possibly even with copies stored on a thumb drive at a family member's house). This might be a little off of the original post's intent, but who cares. Maybe this info can help safeguard your house and preps so everything you have worked hard on and put time, effort, and money into is still there when you get home from a long day of work.
