I think the main thing that upset the C of E was the use of Manchester Cathedral for a gun based massacre inside the identifiable building. Over on this side of the pond in the UK, gun crime is still very very low. (i.e. we don't have the "right to bear arms or arm bears". Handguns are illegal.)
You need to check your facts again. UK's gun and violent crime rate is many times that of the US and has steadily increased after banning guns while the US rate has been in a steady decline since like 1930.
