Keith ,
When terrorist attackers have to resort to using knives in their attacks you can see the benefit of not having semi auto centre fires available to the general public.
It would seem that you have missed an important point. The terrorists didnt go away when you eliminated your center fire auto guns. They simply changed their MO.
Im reasonably well enough informed to know that crime, especially violent crime, has not gone down in the U.K. since the massacre in Dunblane. And, that a knife attack is by no means a rare or odd thing in London. Quite the contrary.
If you are content with the way things are, more power to you.
I have my own belief on the many Gun Free zones that cropped up in this country over the last thirty years. I believe it was a deliberate, and well understood plan by those who championed it to unleash criminally ill individuals on those rendered completely defenseless by those who supported this legislation, in an attempt to invalidate and eliminate the second amendment to the US constitution. There were those who clearly understood that the mayhem and killing would be directed at the most vulnerable targets by the criminals who would know enough to pick a soft target, in order to take as many innocent lives along with them on their trip to hell.
They knew it, they understood it, and they did it. They are now, and always have been, aligned with the left of center political spectrum in this country.
They have a lot of blood on their hands.
Best,
Ted
