042 Rights vs lefts, wrongs and respect

An organisation of street events is asking photographers to gain verbal permission before shooting in a public place. The organisation, The Petapixel article that got us thinking. These are events that are about personal expression of sub-culture but how do we judge or decide between rights of photography in a public place versus respect of individuals? Is this a slippery slope? Is there a difference today from how digital natives will view the rights and risks tomorrow? Are we going to see a change in fundamental rights of photographers? Would that drive a positive or negative scenario? Would technology innovation out pace the revision of law? Will photography become about wearing a nanotech sensor on you jacket? And BTW, weird that this all happened in San Francisco which is one of the most liberal cities going!
