I am not shocked that you have that rule. I am a little surprised that your local police comply with your rule, but I suppose that because you live in Norway.
What I am shocked by is the news that you have had police visit your home a few times and that military personnel have visited your home. I assume that all of those visits involved official business, and I now wonder what the heck goes on in your home that causes police and military personnel to enter your house.
I'm 70 years old and live in America. Police have never had reason to enter my home or my parent's home when I was a child; and the only military personnel who ever enter my parent's home was me when I was in the Navy and my nephew when he was in the Army and neither of us went home with weapons.
So what kind of mischief or crime goes on in your house?
