I have been lurking on this list for a while so I might as well introduce myself :)
As many of us I used to enjoy photography in childhood, I had some pretty crappy off-brand Pentax screw mount cameras and lenses but I did enjoy it immensely. I took a 10 year break from photography in my teens but for the last 5 years I am back starting with many assorted C*non digicams and slowly migrating to 35mm Pentax stuff with occasional dips into MF and LF. I still own a decent 4x5 kit though I don't use it except when completely out of my mind and willing to lug along the monster monorail. I am currently using *istD with two of the venerable limiteds and assorted other glass and am in the process of building myself a light yet sturdy 6x12. Now on to the topic - I have never taken great interest in street photography but on the occasional streaks I get I sometimes carry around my digital voice recorder (most of the time even without the batteries). If somebody comes up to harass me I take the voice recorder out, ask them if they object to me recording our conversation and explain that they are harassing me at the moment and that I would like to have a recording of their conduct to support my pictures (none of which are of them) in court if it ever comes to that. Usually they go away. If they don't I push the button on the recorder and say that if they object to me recording our conversation we have nothing to talk about and they should go about their business and leave me alone. I usually drop something along the lines that they are taking my time which I could use for taking pictures and that I could even sue them for lost profit and that if they are so ignorant as to come and accuse me of something they probably don't even know the extent to which this could be taken in court. I am making a living here yada yada yada... where should I send invoice for my services... bla bla bla... I think there is absolutely no point in discussing any of the tough concepts like freedom or anything of the sort. That is usually a dead end. If they want this to be a paranoid society I just push the voice recorder in their face and make it a reality. Krisjanis
