The most important info:
- He bought a deactivated gun in the darknet ( gun was deactivated in 2014 )
- Reactivated it once he bought it
- Gun was at first sold in Slovakia, article doesn't mention where it was sent from
- Article doesn't mention where ammo came from
This is why I've always been against markets allowing weapon listings. The community really doesn't need the sort of attention that comes from something like this. We already have well and truly enough LE attention.
