Criminals get arrested, told their miranda rights, and taken in front of a judge. They get to see who arrested them and the opportunity to confront them in a trial of their peers. That's how the law works.
The one with the feelings hurt that these people get these rights is you, not me.
Ultimately, by skimping on the law, what ends up happening are mistrials and the federal government having to pay off civil lawsuits for wrongful arrests.
