THE global justice movement is often dismissed as a bunch of leftie liberals moaning about people making money.
But lurking behind the bearded graduates with lofty ideals are genuine troublemakers with a thirst for publicity at any cost.
They have hijacked a notoriously loose organisation for their own ends and are capable of causing massive disruption.
Just think back to the riots last year when thousands piled in to create havoc after what began as a family protest at the police shooting of a London man.
The global justice movement claimed it was people protesting against capitalism and a lack of jobs when really it was just yobs having the time of their lives.
The movement is characterised elsewhere by massive citizen protests at most meetings of the G8, World Trade Organisation, International Monetary Fund and World Bank for the last decade.
It came to the attention of many when activists successfully used protests to shut down the 1999 WTO meeting in Seattle ( above).
But there have also been protests at the 1988 World BANK/IMF meetings in Germany, “IMF riots” in Chile and “water wars” in Bolivia and South Africa.
The Olympics – with its billion dollar sponsors and huge corporate ties – is a perfect target.
Our source said: “This is a dangerous threat because it is so difficult to police.
“There will be legitimate protests held during the Olympics, we are a democracy and we don’t want to turn into Syria.
“But these Anti-capitalists use legal protests as a way in before causing havoc, whilst they’re less likely to cause death and destruction they cause fear and panic in members of the public.
“They stop people feeling safe which is the last thing we want.”
