I can tell you for sure the soldiers guarding The Queen will beat you to a bloody pulp.

I recall an incident back in the 1980s when H.M. was returning on horseback from some parade, and some random nutter just lunged forward. The nearest soldier just went Full Metal Ballistic at the nutter and tackled him down as flat as a pancake. Then the constables came along and flattened him a bit more.

The rest of the onlookers were as described — looking on with approval.

You’ll have to search the Internet for that incident — it’s in the news at the time.

The newspapers later interviewed the soldier. If memory serves, he was quoted as saying that he “felt that raw anger” at seeing H.M. on the verge of being attacked.

I don’t think it would be much different today.
