Security around world leaders has always been a major issue and in the age of global terrorism it is even more important.
America claims the Secret Service who protect the President are the best trained armed guards in the world.
Hardly surprising when you consider there have been assassination attempts, of varying degrees of success and common sense, on every president since Richard Nixon.
So it must have come as a shock to a major European nation when its Prime Minister was hospitalised after being struck by a model of a cathedral.
Silvio Berlusconi is far from popular in Italy and has been the butt of more than the occasional joke abroad.
But when you resort to propelling tourist souvenirs do you not relinquish the high ground?
At both the G20 in London and in Copenhagen there were reports of vandalism by young people dressed in black wearing gas masks.
Anyone who was in London in April this year will tell you of the stark contrast between those there trying to make a genuine point and those clearly there to make trouble.
Of cause these are not the only events this year which have got us thinking about what means we use to attain our ends.
When two British soldiers were killed outside Massareene barracks in Northern Ireland in March it did more to cement anti-nationalist sentiment than the Good Friday Agreement.
The people of Ireland, both Protestant and Catholic, united for the first time in nearly a century determined not to go back to the days of road blocks, peace walls and car bombs.
But what about world leaders?
Recently at a state dinner in honour of Indian Prime Minister Manmohan Singh at the White House two people gatecrashed, and despite not even being invited met President Obama.
When Obama was running for President there were fears he would become a target for assassination attempts from white supremacists.
In fact a plot to kill him at the Democratic National Convention in Denver was foiled before he even accepted the nomination.
This in turn has let him open to political satirists.
One comedian pointed out one of the reasons people were so behind a black president is because you knew someone would try and kill him.
Then of cause there is the now legendary joke of the problems the Secret Service were having protecting Obama because every time they shouted ‘get down’ he started dancing.
Of cause the gatecrashers, like the man who dressed up as bin Laden for Prince William’s 21st birthday, meant no harm, and it seems in most cases the attacker was mentally unstable.
The man who threw the porcelain model at Berlusconi had apparently suffered from a mental unbalance, and Chester Plummer attempted to kill President Ford by walking across the White House lawn and hitting him with a three foot length of metal piping is clearly lacking some creative cunning.
And now allegedly mentally unbalanced women are jumping the barriers at midnight mass to attack the Holy Father. Admittedly the Pope wields less power than in the days of Machiavelli but several of the substantial security presence looked stunned and casually made their way back to attend to this global religious figurehead.
It is true the public need to be given their chance to voice personal displeasures with our leaders. But surely in this era of global threats and Patriot Actesque laws this should not be happening, and why do we still so often resort to violence.
Maybe this is the time which will produce the next Dr King or Ghandi?
