All operations as a public institution should be transparent. We fund them through taxes, we have a right to know what is going on.
I don't know what you are getting at with "self serving and harmful to other citizens"? Like a private institution? a company? Of course private companies are self-serving. All of them could be described as perpetrating some subjective and nebulous "harm". There are already transparency requirements for businesses, and they are subject to warrants. To the extent that they are public institutions (monopolies, publicity-traded companies), there are increasing demands for transparency and vice-versa.
Individuals have a right to privacy and protection from undue search, regardless of scare quotes employed, unless they are living on a prison island such britan.
