- 911, what is your emergency?
- Help me oh god! ... My husband he's going crazy he got a shotgun and is threatening to shoot my kids he...
- [garble garble]
- [Distant voice of a man] "get the fuck off that phone"
- [Loud bang]
- [Line clicks and goes silent]
The 911 operator can try to call back to get confirmation, but a lack of response just underscores the seriousness of the situation. If the police didn't rush over in full SWAT gear, ready to save the lives of children, they'd be the ones l̶i̶a̶b̶l̶e̶ berated in the media for not taking a clear imminent threat to life seriously.Though I doubt fake swatting calls are so well produced.
edit: In this situation, whether real or not, obviously the police shouldn't murder people. If this was real, they should first exhaust their non-lethal options for keeping the crazy husband from murdering children. If it's a fake swatting call or the wrong address, they should discover that and especially not murder people. But in response to the parent's point about the police being eager to rush over from a single phone call, this seems like a 20 second phone call where they have no ethical choice but to rush over. How they behave when they arrive is a different topic from what I'm responding to.
