Dutch LE thought they were smart but they just crossed the line and their entire operation is very likely to get them into huge troubles. First of all this is unprecedented, at least in Europe. This was not a simple Honeypot. They ran, hosted and maintained the website and willingly delivered drugs to consumers acting just like the Hansa admin for a month. They didn't took in consideration that someone could do an overdosis from the stuff they were selling, this is proved by the fact that they only removed Fentanyl in the last days. To make a metaphor it would be the same if they would have sold those drugs on the street for one month in order to later arrest the buyers. During one interview when asked if the police was selling drugs they were very uncomfortable with it. All this is good material to prove they were acting out of the legal scope. Especially if you are Dutch I advise you to write to prosecutors and ask them to open an investigation on the Hansa operation.
Go on, try it.
