Illegal imports / workshops converting replica weapons into useable ones. Dunno how to access it (can't be bothered to find out I mean) but such stuff is probably sold through the Dark Web.
//imported from eastern Europe thanks to Schengen.//
Er...but the UK is not in the Schengen area.
The smoke and mirrors that have developed from this tragic event are astounding. Anybody who wants to shoot people dead (including his own mother) will not worry about the legality of the gun he uses. It's easy to acquire a shotgun without a licence. It's fairly easy to acquire other firearms which require a firearms licence. To somehow now blame the police is simply crass. The bloke was a nutcase, plain and simple and if he had not held his shotgun legally he would have acquired one illegally.
I am with ummmmmmmm on this. I have NEVER even had a parking ticket, but believe I could get a gun in 2 hours no problem. Has anybody actually been in to a south London pub? I do not mean a family friendly Brewers Fayre, a proper old boozer type one. And I am not even from London!!
