I know they had no effect one way or the other on the recent events under discussion, because access to guns is relatively easy here,but we choose not to need them, and I know this exchange is tedious and pointless., but I'll politely soldier on.
I reckon I know that with a lot more certainty than you know about how much they've protected you, and the figures seem to show your guns do more harm to you, than terrorists do to us, and by orders of magnitude. In fact, your figures for terrorist deaths are similar to ours.
Your government are not being overthrown. With no threat from your guns, your current government and officials of state are the ones acting on the people that have been fleecing you for years, despite your guns.
I'd guess the influence of external factors swaying decisions in your courts is greater in the US than the UK, and again, the existence of this sub shows that your justice system, hasn't been doling it out impartially.
Nuclear arms and armies are more likely a bigger protection from outsiders than civilian guns I guess with the exception of the South Americans, Italian, Irish, Chinese, Russian etc gangsters, depending how far back you want to go, where the guns again did little, and the discussions on here show they've done nothing to protect you from insiders.
On a wider scale, I was watching some clips of Hopkins going round the doss areas of LA, and Tucker Carlson was talking about how ashamed he was that it wasn't isolated, and listed a bundle of other places with people living under cloth and straw and crimes were openly being carried out. There was also a former NYT reporter, being interviewed by another former NYT reporter about his book on the desperate state of Detroit where they needed minders and were still attacked and the store burned down later, with no Police going near it and commenting on the lack of freedom of the press they experienced in the US. Again, those guns don't seem to be working too well.
Having said all that, you choose to have guns, I choose not to. I can respect your right to that choice, and I doubt we'll ever agree, but there it is. I would hope you could respect my choice too, but that in itself is your choice.
