This relates to the Science of Jurisdiction/Law and Philosophy of Law.
As soon as the letter of the Laws is broken, the rights for absolute privacy fall away by definition and the perpetrator(s) fall(s) into the category of possible persecution (by law enforcement, first and foremost)! Note: However, as a crime (letter of the Laws...) has taken place, everyone has either the duty or possibility to file a report to the Police about their "suspicions"/sightings/what they've witnessed!
Note: I'm inspired by Nancy Grace and we may share some "context" here.
