I dont think people are so upset about the mans motive; to educate people about surveillance is a good thing. the problem is 90% of the footage captured by public CCTV cameras is different. Municipalities in the US that receive funding for CCTV cameras do so likely as part of a Homeland Security grant from the federal government and will install low-resolution cameras typically at intersections as government buildings have already been covered. These low resolution cameras are typically designed to reduce the cities expenditure on insurance for police and emergency services as they blow through red lights far more frequently and thus have a greater potential for collision with an automobile than does the average driver.
The footage is, in my personal experience as an accident victim, uselessly low quality and low framerate.
as for private surveillance, ATM video is hillariously low quality (check out youtube for a few examples.) higher end DVR systems in stores and pubs however are only used during an altercation or when required in order to prosecute a violation of law. nobody of any importance has interest to this video.
what the privacy evangelist is doing in contrast is uploading people to a distributed global network of video content which is freely available to anyone at any time. It serves to educate the public about google more than anything else, which is good. Given the potential for my boss, my coworkers, or my loved ones to stumble across the video however, I cant say id think twice about landing a haymaker on the first glasshole to shout "record."
