Can the police be warned in advance?

Yes, and it's useful when threats announce it explicitly. A prior report, filed with screenshots of the threats, is logged and can be taken into account if a call comes in later. It guarantees nothing, but it's the only real preventive measure available.

Why don't emergency services detect the call is fake?

Because an emergency service must respond to the risk described, without being able to verify it beforehand. Treating a call as fake would be far more dangerous than intervening for nothing. It's this obligation that the technique exploits, not a failure on their part.

Swatting (fake emergency report)

In plain terms

Someone calls emergency services and invents a serious emergency at your address. A real intervention gets launched at your home, with police officers who have no reason to doubt the call.

Definition

Swatting is causing law enforcement to intervene at a person's home by falsely reporting a serious situation — a hostage-taking, an armed threat, a bomb threat — in order to harm them.

How it works

The perpetrator needs only one thing the victim doesn't control: their address, obtained through prior doxxing or by cross-referencing information. They then call emergency services describing a situation that demands an immediate, top-priority response. Emergency services cannot treat such a call as suspect: their duty is to intervene, and that obligation is exactly what the perpetrator is exploiting. The intervention is therefore real, and its danger is too — the person targeted doesn't know why officers are entering their home, and a startled reaction can be interpreted as a threat. Swatting frequently follows a harassment raid, of which it represents the escalation into the physical world.

Warning signs

Your address published in a hostile context
Explicit threats announcing an intervention or a "visit"
An ongoing harassment raid, with attempts to find your location
Calls designed to confirm your address or that you're home
Unsolicited orders or deliveries at your home, often as preparation

How to verify

There's nothing to verify during an intervention, and trying to is dangerous. Prevention happens beforehand: knowing whether your address can be found, and having reported it if threats announce one.

What to do

During an intervention: keep your hands visible, follow instructions without sudden movements, and don't explain anything until asked to. Explanations come afterward, once the situation is secured. This is the only conduct that protects everyone, including you.

If it already happened

File a police report: a false report causing an emergency-services intervention is a criminal offense, and the call leaves technical traces that can be used. If threats announce a swatting attempt, report it to law enforcement before it happens: a prior report is logged and can change how a later call is handled. Have your address removed from the places where it was published, and document the raid or doxxing that preceded it.
