The police act as agents of the state, as a function it is performing a public function. it is established to act on the public' behalf. When a state actor, the police here, clearly bends their role to push for more information, essentially fishing for more information, even if it does not exist, is the same as a reporter fishing for information based in nothing more than air.

We would not permit the examination of personal documents of the pm's family because of nothing more than air.
It is all about money, they want to make money and this reporter is trying to make work for herself by shouting they are hiding something cuz I can shout it.
