To summarize the statement in English
The Swedish Police just released a statement about how they recently identified about 3000 buyers in Sweden and over 20 000 purchases of drugs through the Darknet together with countries such as USA, Netherlands and France amongst others.
"We're in the early stages of a big investigation, we don't know how many of these buyers that can be prosecuted but it should be known that you shouldn't be able to feel anonymous and safe buying drugs through the Darknet"
Sounds like some fear-mongering to deter buyers, hopefully we won't see people buying small amounts getting hunted down, it's so ridiculous. They've also released a statement on Facebook, describing how dangerous drugs such as Fentanyl is purchased through the Darknet with lots of shares and comments like "Good job, thank you for keeping the streets safe" and "I hope that you catch every single one of them"
Sigh.
