Whatever happened to confirming the suspect is actually at the address before entry?
If you haven’t done anything wrong, and you don’t know anyone who has done anything wrong, and you don’t live anywhere near anyone who had ever done anything wrong, and you don’t have a dog or a senile parent or firearms in the house, and you don’t panic and you keep your hands where the police can see them at ALL times, then you don’t have anything to be afraid of in a police “house call”.
What’s the big deal?
