A friend warned me and now my window A/C appliance is gone

My cousin is an alarmist. She basically said she had read where someone was taking air conditioning appliances out of the windows of dwellings. She kept telling me I needed to secure all of my window A/C appliances so no one would get them. I lived in the middle of a gated community. I couldn’t figure out how anyone who didn’t live in this particular community, could get inside the gates & steal something similar to an air conditioning appliance. Not only that, but all the people in our community had central air conditioning. If you had a window A/C appliance, it was most likely in the attic window. That would be quite a feat to get up to the attic & steal an A/C appliance without being seen. I laughed at Johnny when he started talking about the thefts. I told the guy how deranged that was, & I dismissed his worried actions. A week later, I was on my way back to my lake dwelling & I saw a Heating & A/C repair van pulling out of our community. It had a couple of A/C appliances on the back of the truck. Every one of us often saw odd repair vans inside the gate. I honestly thought nothing about this one, assuming a few people had modern A/C appliances installed. When I got back to my property, I parked in the garage & never thought to do an inspection of my dwelling. I was going into my lake dwelling & not entering some unknown hotel. I wish I had taken stock of my surroundings. It was something my partner was regularly telling myself and others to be aware of your surroundings. While I was at work, someone had managed to take my air conditioning appliance, & it was absolutely in the repair van that I had seen.
