This is not the first time. But both this guy and the last who was discovered were tiny workshops making stuff by hand, on orders, and charging the earth for them. This sort of thing is certainly not going to arm every thug in London - few of them would have the contacts, and most could not afford the prices. In point of fact, gun ownership among London's thugs is low, and most of them use knives. My friend mentalguy found the very expression "knife crime" bewildering; it was not an expression used by the US media, or a concept they embraced. But it is the daily bread of British newspapers.
