“...police have to verify that the guns actually posed a threat...”
There’s the police on the bad guys side again. Some blue lives matter.
The police are NEVER on the side of ANYONE. They want to arrest you and they want you to be convicted. It is core to their training, which is edging close to brainwashing. There are some cops who have the ability to apply common sense, and even a few who respect individual rights. But there are more who would do their damnedest to put you away for a misdemeanor, even if it was committed to save your home or family.
