Ming's in full voice somewhere, ranting on like every forum amateur about mall rentacops interfering with his right to photograph anywhere anytime.
This is one of The Most Common threads on any forum you care to visit, and the text is always pretty much the same. I have rights, the law this, the law that, plus which, everyone ought to be super happy to be photographed, because I know more about marketing than you do, and anyways my ideas about how you present yourself to the world ought to trump your ideas.
Photography is an appropriative act. We take a picture. The intellectual property rights held be a photographer, while generally clear and strong, legally, are in fact rather tenuous and thready when examined carefully.
What is particularly maddening about this particular dumb argument is not that is ignores the very real issues (mall tenants have trade dress out there, and is behooves the landlord to at least make a show of protecting the tenant's IP; mall customers may not appreciate some dipshit with a giant camera taking Street Photographs of them; and so on). No, what is maddening is that the argument always contains the planted axiom that the other guys should be happy I am here being a pest.
I take pictures wherever and whenever I damn well please. I am OK with that because, ultimately, ain't nobody getting hurt. Feelings may get bruised, but I'm not actually hurting anyone physically or financially. But. I don't insist that you be happy about it.
The whole you should be happy about it appears over and over again when some weasel wants to steal shit. People illegally download music and movies, and insist that the artists and studios should be happy about it, because, exposure! Creatives steal software and insist that vendors should be happy about it, because, exposure, and I wasn't going to buy it anyways! And around it goes. An incredibly high percentage of people who make intellectual property also steal it, and then insist that the victims be happy about that, because exposure.
It is left as an exercise to the speculative reader to guess why the weasels insist that their victims ought to, if only they were sensible, enjoy the process of being robbed.
