David S., the Munich gunman has purchased the weapon on the Dark Web, sincerely I was waiting for this title in the headlines, but . In Germany, it is quite difficult to pay for weapons so how the gunman got a 9mm Glock 17? It is still a mystery, the German authorities are still investigating the case, the unique certainty is that the Glock carries a certification mark from Slovakia. This means that someone has converted the weapon from non-functioning to being a killing machine. David S. was obsessed by mass shooting spree, inspired by cases like Anders Breivikmassacre and by the Winnenden school shooting attack.”]
