Regarding seizure of media footage, I've heard some thoughts before about schemes such as wireless-enabled cameras to send data remotely asap. There are definitely a wireless camera or two out there, but nothing that does it automatically, AFAIK. Anyone have any hints or tips?
Update, 30th Sep: Well, Blair and Straw have apologised now that Wolfgang (suspected terrorist) has become a national hero - it's amazing what a little press coverage can do. No such grace, however, for the 600 innocent people stopped and searched throughout the conference*, or for the various local people getting arrested for bearing anti-blair slogans, under the anti-terrorism act, no less.
Hecklers, protestors and people doing nothing are all terrorists now. This turned into a comedy farce a while ago.
* An unmissable quote from the police spokeswoman:
"By definition, many totally innocent people going about their normal lawful business will be stopped and checked," she said. "This is what creates the deterrent for terrorists."
There's definitely a push for the norm to become a population of innocent people prepared to put up with whatever crap the police push onto them. The true effects of this continue to go unquestioned.
