“Hasn’t happened anywhere else with the Castle Doctrine.”
It already happened before the current law in Minnesota.
In 2007, a police swat team broke down the door of a family in Minnesota. The father responded with shotgun fire, and stopped the assault.
The Vang family later received a large settlement from the city.

I can't imagine the SWAT thugs not burning the house to ground and killing everybody inside, though.
There must have been TV cameras nearby.
