> We have a law that we may not be required to quarter soldiers, perhaps a better law would have been to make it illegal to enter private property without consent armed.

I believe that a warrant gives them this right. But the give a bit more nuance there is a difference in entering armed vs drawn. We should definitely have a high standard for when weapons are allowed to be drawn. It is in fact the police who are in a position of power, so they have the higher standard to meet.
