Silence, on tourne !
Many, many people used their camera-phones to film or snap pictures of the events, something which is bond to become increasingly common. The quality of these videos and photos, given the conditions, is obviously quite bad (some can be seen on the web), so it's more a matter of saying "I've been there", I guess. But with the quality of the camera-phones increasing steadily, better and better pictures will become available in the future.
In fact, everybody is filming each other: the people, the police and the media.
