Horrible though the events of yesterday were, serious attacks on MPs do seem to be very rare. Historically, most of the deaths, not entirely surprisingly, were the results of "The Troubles" in Northern Ireland. It would have been nice if the cessation of most violence relating to that had brought an end to all such occurrences in the UK, but it was never that likely. Some people just seem to search for an excuse to bring misery and pain to others.
It's not just the MPs and other senior political figures who suffer, when Lord Jones (then an MP for my constituency at that time) was attacked with a sword, an assistant, Andrew Pennington, received fatal wounds trying to stop the attack, and posthumously received the George Medal. I'm sure there are many other instances where bystanders and helpers have experienced appalling effects upon their lives.
I still recall those events, and far too many others over the years, by people who think that their particular political, social or personal justification is adequate excuse for extreme violence, sometimes against those who have little or no control over that cause.
People like MPs of all political flavours, who feel a moral obligation to have surgeries and other events, must accept that they have an increased risk of violent attacks against them, but continue to expose themselves. They know that it's important for the useful and correct function of politics and government in this country, and I applaud them all for this.
RIP Jo Cox, an honest and strong woman, who obviously believed in a better world for all, and was willing to put herself at risk attempting to ensure that.
