Donthave you are being deliberately obtuse.
The theme running through your posts is that US gun control should be more lax. More people should be able to own guns whether that be semi automatics or just plain handguns. We are trying to point out to you that our tight gun control means that mass shootings are so rare in the UK, they stick in the mind and we talk about them for decades. They never get forgotten.
I can remember every incident in my lifetime, where I was, the name of the aggressor and the aftermath. It's such a huge awful tragedy, the nation is shocked to its core and no one forgets. Hungerford was the one that sticks in my mind - after that happened, this then happened.
The Firearms (Amendment) Act 1988 was passed in the wake of the massacre, which bans the ownership of semi-automatic centre-fire rifles and restricts the use of shotguns with a capacity of more than three cartridges.
Nothing happens in the US, except a lot of rhetoric and shouting and people like you advocating more guns and less gun control. Massacres are a way of life in the US. There are so many that people are somewhat immune to them, (except the poor victirms families) I won't quote you figures but it's more or less a daily occurrence.
Yet you are still here arguing that your way is best and that there should be no strict gun control areas and not only that, you would like all this madness brought over here!
Yeah right... you are prepared to sacrifice the lives of children so that people like you can be tooled up to shoot and ask questions later if someone should dare to pickpocket you or try and take anything you own. You need to have a long hard look at your priorities.
