I’m positing an ethical opinion, not a legal one. Entrapment means “the state of being caught in or as in a trap”. As well, “the action of tricking someone into committing a crime in order to secure their prosecution”. Both definitions apply here. It's the difference between law and order (courts and cops); and truth and justice (rational thought and honesty). If not for the deliberate actions by the KPD, there would have been no crime committed in these cases. They probably still would have committed the same offense elsewhere, just not with these cops. We can’t know for sure nor just how convincing the KPD posers were.  I agree with your last observation.
