Having participated in the various demonstrations today (Saturday 14) in Copenhagen these are my impressions. After the international demo the disobedient bloc marched to a prison where some of their activists were being held. I myself joined the Anarchist demo called to protest 'Against Police State Europe'. Neither of these demos were organised with the state authorities yet both demos managed to link up at the prison! At this point however, the march was subjected to some harassment by the police. But despite this harassment the disobedient bloc managed to force its way past the police vans blocking us in when we sought to leave the prision and march back to the city centre.
After this success the police then sought to split the demo as it reached the city centre. The good organisational tactics of the local anarchists paid off at this point. Over a PA system they urged everyone to form chains by linking arms and to stay together. On the whole this tactic was rather effective. Even so, the police still tried to grab anyone wearing a mask; many tense moments ensued for the next hour. I saw the police attempt to break into the crowd twice, and I saw one person dragged away.
Overall, however, the general solidarity amongst the crowd was supurb! If only we had tried this tactic in Oxford Circus back in 2001!
