As has been repeatedly pointed out by British posters here, and contrary to a persistent myth among US commentators, the British citizen has every right to defend himself, including if necessary the use of lethal force, and that right derives from neither government nor the police. It derives from centuries-old Common Law on which both the US and British legal systems are based. You are of course right to say that it’s the individual’s responsibility to be prepared for whatever risks he might be exposed to.
That, however, is a completely different matter from your repeated and bizarre claim that the Scottish Highlands are a particularly violent or dangerous location. It doesn’t alter the fact that the risk of any individual being exposed to violence when visiting the Highlands is vanishingly small. I’m not sure what point you are trying to make by repeating single examples of crimes that have taken place there. Of course there have been violent crimes. Mankind is imperfect, individuals are wicked, evil acts are perpetrated. Is there any country, however civilized, where that is not so? None of what you have said even begins to demonstrate that, against that universal background, this area is relatively dangerous.
The average murder rate in the UK as a whole is 1.2 per 100,000 people. In the U.S. it’s 4.8, four times as high. What conclusion do you draw from that? If I had more leisure than I can lay claim to, I could probably mine from the published statistics the figures for the Highland Region. I would be very surprised if they are not a good deal better than the UK average, as this is true of most rural areas of the country.
Yawn.
