On a similar note, uploading videos and photos from protest flash points might lead the police to arresting the wrong people (ie. not Clegg and the other lying cheating scum politicians, bankers etc). Be very careful about what you publish as there is no point in helping the cops/state/mainstream media in devising and destroying our movement. That said, your photos/videos may prove vital to somebody arrested/assaulted in mounting a defence or making a complaint. It would be a good ideal to inform the Green and Black Cross Legal Team ( GBCLegal@riseup.net), about potentially useful footage/photos, as they are helping to co-ordinate legal support.
Likewise, if you witnessed an incident leading to an arrest/assault then think carefully before writing about it on Facebook etc. If you feel the need to write up what you saw then protect yourself and others by publishing anonymously via indymedia rather than corporate social networking sites or blogs. Make sure that you speak to the Green and Black Cross Legal Team so they can put you in touch with solicitors defending those arrested.
