The advent of the video camera radically changed protesting. Now it was safer, since the presence of video ensured the authorities would, in most cases, only go so far. However, since then, police have ensured to confiscate and delete footage of crucial moments, regardless of the law. Live streaming allows protesters to record events in real time and have clear and convincing evidence if authorities confiscate their devices. Further, since the footage is stored on an external server, it cannot be easily deleted. Ustream in particular, has a large record button on your smartphone’s home screen, allowing easy access to the stream when seconds count. This link goes to Ustream, but check out competing services such as Livestream and Bambuser to find out which one works best for you.
