Yeah, it seems like they take the seriousness of the threat into account when determining the response, but not the plausibility of the threat. If there's a 1% chance that the house contains a deranged gunman threatening to shoot his family and then himself, that probably shouldn't be met with the same response as a 30% chance of the same... There are probably a lot of situations where it's a tough call though.
