Here is where a judge needs to read the laws that he is suppose to up hold and learn from what really happens.
A police was on National News for using Facebook to collect pictures of local naked boys who were in Junior high School. Was it an authorized sting approved by his police department of a warrant by a judge? NO! on all counts.
He used his niece’s information to lure boys into reveling themselves. The overt act was by the police in many ways.
Use of an innocent child as a means to self gratify his wants and desires.
Getting the boy to expose himself by using his feeling towards a girl from his school.
Entrapment tactics not approved by any known law.

A boy committed suicide after his roommate posted him on social media and the campus police said it was okay to expose people like him..
Considering that same sex rape occurs just like in prisons then who was the aggressor.
They treat the other person as a replacement for a woman they can not get.
That right most of the sex done in prison is by people who claim to be straight, but has no woman to do it with.
The only difference is that in the free world you have social media devices to spend millions of times to everyone. In Chicago at a Police Station a decade or so ago 3 officers got caught running a sex web site.
The claimed it was a sting operation to get identities of pervert.. No warrants, no supervisor approval, no legal authority at all. But their bank account set up for the site proven fruitful at $79.95 per visit to the website.

Take what the Federal Judge with a grain of salt and check to see whether they had gotten the proper documents to do this.
