It's really easy to say that when you're not the one calling the police because there's an actual madman with a gun holding your loved one hostage. I think it's a tough situation that, really, has more to do with the overall culture in America than how emergency services respond to particular calls. If the overall level of potential danger was lower due to cultural reasons, I think then we could talk.

Showing up with 20 swat cars doesn't mean that there's 20 swat cars blindly shooting at the house.

There's no harm on just showing up. As long as they verify the claims before acting on them, I don't see the issue.

The only issue is that it is expensive and may break a door or something. Which is why the caller should be tracked, and made to pay for all of it.
