Equalizing mass surveilance.

moerty writes: the advent and application of video surveillance by governments on its peoples has been a worrying trend in western society, the recent incident with the UCLA student getting tazered highlighted a shift of power where surveillance in the hands of civilians can be used as an equalizing tool against government oppression. Unfortunately the video and sound quality left much to be desired so i ask the slashdot geeks, what are the best optic/sound capture devices for such a situation? A plus is having as inconspicuous device as possible since photographers in major protests have been beaten up for their cameras, a major dream is to have offsite storage. As a follow-up, what organizations exist that encourage the use of the camera as an equalizing tool?
