I think historians of the future will ignore most of what we say or write today and instead look at our actions. The fastest growing artform in our society is photography, yet it's become closely associated with our biggest cultural fears: terrorism, loss of privacy, and the abuse of children. Some undergrad in 2064, then, will likely have to write a paper or two about our changing relationship to photography on the street.
Are there any items in today's news related to that thought? I'm glad you asked, because there is in fact something you may find interesting:
Photographers protest against police use of anti-terror laws
"Trafalgar Square was lit up by flash bulbs this lunchtime as thousands of photographers demonstrated against police use of stop and search. The event was organised by the campaign group, I’m a photographer, not a terrorist, following a series of high-profile detentions of photographers under section 44 of the Terrorism Act 2000. Official estimates indicate that around 2,000 amateur and professional photographers joined the protest."
