Sorry, that's Pollyanna thinking. No judge would ever decline to grant them a warrant. Instantly. No questions asked. They are NOT like any other LE agency. They will have a cop and a warrant there in five minutes, right on your doorstep, if you retreat behind your "rights."
People need to wipe the pixie dust from their eyes.
Really? No judge would ever decline them (whoever them is) a warrant?
I've spent a little time around the courthouse in the last three decades. I have to say that I've seen my share of warrant applications declined, and I've seen more than my fair share quashed.
Prosecutors lose cases all the time because the police erred (read: outright lied) in their warrant application, or because they collected evidence without a warrant entirely.
I have some good news for you. There still are some judges who will not issue a warrant without just cause. My family was fortunate enough to have such a judge when DYFS went rogue on us. I refused to let them in the house. They said I had to let them in, and if I didn’t they’d be back with a warrant and it would be worse, hinting that they’d trash our house. I stood my ground. They never did get inside our house.
