Actually, I feel like you misunderstand the nature of policing in the United States. The officer wouldn't have to go through those many steps to legally kick their way into my house, and then use anything as evidence against me, they just have to cite probable cause.

Probable cause can be ridiculously easy to establish "it smelt like marijuana" "I heard someone call for help" "it sounded like there was an altercation" "The evidence we need for our investigation is reasonably in this location"

I'm sorry to break it to you, but even if there were something wrong the state did while policing, it would be very difficult to prove to the state that the state did anything wrong in the first place.

Shitty, I know, but it is how it is right now.
