I have no doubt that his police friends were more than happy to get him to collect constitutionally protected information on their behalf.
That is the attitude which disturbs me—the notion that one believes it acceptable to decimate constitutionally protected information to the police simply because one is also a government employee.
Apologies for not making that clearer.
Except the information is not constitutionally protected.
His claim was that you need an “administrative warrant” to verify addresses on the internet, and that police went to him/her because they couldn’t do it otherwise.
His claim is categorically false.
