Up here the business is understood slightly differently...
I work for a company that is among other things a security service provider. With burglary alarms the law of the land is that we have our own non-armed response that does the initial check of the perimeter to evaluate the need for police response. The police are dispatched directly only on robbery/assault alarms or to objects such as banks, jeweller's or pharmacies. We get about 80% false alarms, of which roughly half are solved on the phone before our patrol gets on the scene. Technically, that's not bad. Without a proper certification system for alarm installers we have no way to control who installs what and how as an "alarm system"; if it fills the basic requirements we have to take the client or our competition does.
The stuff we install ourselver or thru our self-certified partners gives no false alarms for technical or installment reasons - and the ones caused by personnel on-site are 90% solved on the phone. Training the client to communicate with us is an important part of the service.
Our guys are supposed to report and wait for the po-po to arrive if there's a hole in the perimeter. They never go in to get anybody out. What they do is place themselves right and wait - that's what they train, how to approach an object, use the vehicle right, what to look for, how to communicate and report, how to retreat safely in case. They carry ASP's, OC, handcuffs and such and wear body armor. Some patrols use dogs too, mostly to search thru construction sites and such on normal rounds.
What we get like this is zero injuries on our guys - no security officer was killed on duty for the last 30 years in the country. The criminal element is well aware that our people don't carry and very rarely carry themselves, let alone use what they carry. That they reserve to other members of the subculture. Brandishing an illegal firearm to fend off a security guy isn't worth the sentence compared to just giving it up if too slow to get away in time (we tend to be able to arrive on scene in around 7 minutes average).
Edged weapons are the problem, they are carried more frequently and that we address with the tools and training we give our guys.
The basic difference is that we just about never have to respond to a hot burglary. Our installments are very rarely even built to include a separate perimeter to activate while at home - there's just no demand. Burglaries happen on cold objects; once again a result of conveying the message that people should no be harmed if getting at property is the criminal's goal.
The insurance companies work closely with us. The burglary as itself rarely is the real problem for them, the afterwork is - or its absence. In our climate a smashed window will freeze over the whole building's central heating during a weekend if not repaired. A busted waterpipe will do much more. As a result we have nearly as much alarms from heating systems and humidity sensors as from burglary alarms.
What makes the interaction between the criminals and us (and especially the police) such in nature, that gunfire is very rarely heard, is remarkable though. I mean, the police are very well armed and trained (Glock 17s and 19s personal with H&K MP5's in cruisers, with some odd S&W revolvers and hunting rifles/shotguns still around) which gives the possibility to cop-aided-suicide, but that doesn't happen while committing a burglary or even robbery... the ones who try that are drunk at home, they just don't have the guts to do it themselves so they call the cops and say: "I got a gun, come and get me. " Even these are very rarely flushed out thru an assault - mostly securing the perimeter and letting time do its job will lead to a bloodless solution.
The ones on a burglary scene seem to have a clear sense of still having something to lose. This is as far as I've come in my research...
