The demonstration started on the ‘Spui’, quite quietly with about 200~300 people and no cops.
After the Spui, people went onto the Leidsestraat, one of the main shopping-streets leading to the leidseplein.
The demonstration then went left into the Kerkstraat, where greek bureau of tourism is located, by lack of a consulate. Here the demonstration stopped for a bit. Afterwrds they turned onto the Vijzelgracht.
The police arrived somewhere arround the leidseplein and the kerkstraat, and from that point on guided the demonstration to the dutch bank (as planned).
From the vijzelgracht up on to the weteringschans. The last street before the dutch bank. During the demonstration the usual slogans where shouted and some fireworks went off.
At the dutch bank some people held some good speeches, with stuff how this was not just a greek struggle, but an international struggle, and with that everyones struggle.
The crowd agreed, shouted a lot, but there was no violence what so ever.
After the demonstration most people went to the open assembly/meeting in Amsterdam west-centrum for discussion and socialising.
