I remember being with you at that Reclaim The Streets. Spray was still unusual in those days. The cops used spray on a few people as the party was being set up and threatened many more. By the time the media arrived, the cops were denying they'd even had sprays with them and the media dutifully repeated the line.
These days the cops wouldn't be able to lie like that, and the media would find the phone footage a lot more newsworthy that a police press release. The ground is shifting under our feet.
Talking of which, check this baby out. Mindblowing.
