I feel kind of sorry for the police there, because when a member of the public makes a complaint, they have to take it seriously, even if the complaint is stupid.
Actually, they aren't compelled by the law to respond to anything. In my experience, they move much faster for trivial stuff.
Hockey player turned crazy because his girlfriend is about to break with him, threaten to maim a group of 8 people, none who can physically oppose him = We're not moving
Girl thinks she saw UFOs in the sky = We'll be there in a few minutes
Yes, I speak from personal experience. The second event was a week after the first. And it wasn't isolated cases, I had to call the police at other times too.
Edit: Just to clarify, there
was a UFO. In fact, there was about 20 of them I'd estimate, I saw them. I seriously doubt the objects were alien transportation devices of any kind. And I don't know what the police could do about it.
