- What were the police doing?
- Stole the tents, the police stole the tents, dispersed people, started throwing smoke grenades, that's all.
- How long did it take?

- (About six).
- I remember at least two.
- Was it the police who threw it?
- Well, of course, not us.
- (People threw back bottles of water, plastic bottles).
