A Balancing Force to Mass Surveilance?

moerty asks: "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 use of tasers on a UCLA student has highlighted a shift of power where surveillance in the hands of civilians can be used as an equalizing tool against government oppression. What are the best optic/sound capture devices for such a situation? A plus is having a device that is inconspicuous, since photographers are usually targeted due to the visibility of their cameras. What about off-site storage and the hosting of such videos? As a follow-up, what organizations exist that encourage the use of the camera as an equalizing tool?"
