My wife was chased through her parents house at knifepoint by burglars. She locked herself in the bathroom and was on the phone with 911 as the burglars tried to kick the door in. They had almost gotten in when the cops showed up with sirens blaring. They left.
Two weeks later, they broke into a house a block away and killed two residents.
At my last apartment, I didn't think much of the cheap-shit door locks so I added a hotel-style locking bar for something like $20 - something I'd never bothered to do in the past. When I was out of the house and my wife was home alone, a pair of men in masks (she peeked out the peephole when the battering paused) started trying to break the door down. My very sweet, loves-everyone, 50-pounds-soaking-wet 6 month old puppy let out some very uncharacteristic and very intimidating-sounding barks and they booked it.
These are statistically unlikely occurrences in most safe countries but they still happen. A bit of security doesn't hurt and doesn't really cost much.
I doubt anyone in particular has it in for my wife, but she is certainly not short on bad luck!
The real damage in a break-in for us would be the feeling of being violated and feel unsafe in our own home, and that's not something that an alarm or guard will be able to repair.
People may complain about the high taxes I have to pay in Germany, but at least I never really have to fear for my personal safety or invest a ton of money in heavy home security systems.
It's actually better in that case not to have any alarm system.
So these people have benefitted by having a lower premium because they have an alarm and then not used it / found it inoperable in the event of a burglary.
Stay safe.
"I'm terrified of someone stealing my $400 TV and $600 computer, so I'm going to spend hours and hours of time and lots of money on an alarm system, guns, reinforced doors, new locks, better windows, and a goddamn bubble from The Prisoner."
[0]Pretty sure I heard something like this recently. One factor postulated was that since the price of consumer electronic items and whatnot typically targeted in burglaries has been falling, the risk/'reward' calculation of what a burglar would find in an average house versus the risk of being caught and going to jail is serving to deter potential burglars.
