This might paint the situation in too dire a light, but it seems a legitimate concern to me:
Jonah, the problem is that when someone kicks down a door they are creating an unreasonable risk of violence.
The recent trend in state gun laws has been the “castle doctrine.” So if a reasonable person could be expected to act in compliance with the “Castle Doctrine,” she will be in bed with a gun on the night stand fully confident of the presumption that a criminal who forcibly enters or intrudes into her home is there to cause death, and that, therefore a person may use any manner of force, including deadly force, against that person.
In the end, Ms. Homeowner may not be prosecuted for killing the first three police officers who cross her threshold, and at the same time her orphaned children may not be able to sue the police for violating her rights when they kicked down the door and then shot her in self-defense. Perhaps the courts will determine that everyone was acting within their rights, but the situation is hardly a wash.
