To be honest with all of you,this guy did two things wrong:he ordered parts for an illegal weapon,from a dodgy unlicensed dealer,who probably sold weapons to drug gangs and organized "mafia-type" criminal gangs.Then he ordered hollow-points,from the USA,which is not permitted by anyone,except for wholesalers and gun dealers,who possess section 5 permits and all of the importation paperwork.
If he just stuck to the ammo,he might of got away with it,possibly scott free-instead of which,he bought parts for a fully-functioning assault rifle,from a dodgy illegal dealer,who possibly tipped-off the cops,whilst under pressure,about this guys purchase.They could have confiscated the dealers pc and retrieved files,stating the names and addresses of clients,that had purchased,those illegal gunsThat force probably contacted his local force and the they gathered their armed-response team together,to break into his property and arrest him,for possession of an illegal weapon.
He was probably one of many suspects,on the cops wanted list and was arrested,for possessing that AK47,or the ammo,or for both.
The police probably monitor gun and weapon websites,to stop UK citizens from purchasing stuff illegally from Europe and the USA.This is why I don't want to do this and take the consequences,that go with it.That is how this bloke,who was arrested and sentenced accordingly,might have been caught out-by the cops,who could have been spying on him-from Scotland Yard,NCS or NCIS.
Hollow-points were banned,because Thomas Hamilton used them in his pistols,to kill the kids,in Dunblane Primary School and consequently they were banned,because they were considered unnecessary for target-shooting,because they were designed to expand on impact and were only good for and designed for,killing a person.But they could be used for hunting too,but that would be a no-no.
Micheal Ryan used armor-peircing rounds in his AK47,almost a decade earlier and consequently they were banned,because this round did some serious damage to police vehicles,firetrucks and the police helicopter,because they penetrated those vehicles and seriously injured and killed people.
The cops felt that assault-weapons were a threat to society and to them,because it supposidly jepordised,their safety.They also felt that way about all full-bore slrs-too.
