They should make an early pledge to non-violence in thought, speech and action no matter what resistance they meet and inform the government, police, authorities and security companies about it. It is absurd to protest the development of EU war-fighting capabilities with violence. Better suffer and be harmed than harming anyone. Those who fear that they may not be able to practise the latter should stay away from Gothenburg. Europe needs that.
Violence attracts the media.
But creative non-violent actions could be far more effective. Imagine that 50.000 citizens each carry a few kilos of wheat with them to Gothenburg. Wheat is about sowing seeds and it would remind us of the folly of EU agricultural policies and globalisation. Soft and harmless, it could be poured all over the meeting places, streets and squares and become a happening as good as a the famous buildings wrapped by Christo. We want leaders who practise it with courage, without weapons.
