My parents lived in an apartment, several apartments in our house got broken into. My dad went to a reinforced door company to get a quote. It was almost 10.000€, a ridiculous amount! We didn‘t get it.
A month later we had a break in while I was home alone. He took off when he saw me. We got the door. Now we got a bulletproof 10.000€ door.
To this day I am convinced the door company sent the burglar.
Alternately, there are some burglars that happen to have an informant inside the company giving them tips.
It seems like a great way to identify potential marks, by looking for victims who (A) believe they have enough portable wealth that they are considering expensive security measures and (B) don't yet have any of those security measures already in place.
I assume this is the division between people that consider apartment living the default versus those that consider living in houses with outside-accessible windows the default.
