Sooooo can you set up a meth lab, then add yourself to the list?
A ) I have an illegal thing in my house, but I register for "please dont shoot me etc". Party B calls the police, door is still likely to be kicked in.
B ) I don't have an illegal thing in my house, I register for "please dont shoot me etc". Party B calls the police, door is still likely to be kicked in.
And at what point does it become meaningless if the majority of residential addresses are on the list?
