What is speech? I think that's making any argument you'd like for or against something, the establishment, other ideas, the man, etc.
I think requiring the sign-off of all parties for pornographic videos (or any any other really where privacy is a reasonable expectation) might not be a bad idea.
But maybe it can be generalized. Say video of a person is captured in a changing room at some dept. store, the security guard takes it to try to sell it to a magazine because he thinks it's a famous person, it gets printed/put on the web. Should that be allowed? Now, think, that perhaps even if it was a celeb, they should be afforded the same protection as well?
I think perhaps it can be generalized to situations where the person expects privacy, video should not be released unless it's in the public interest (you catch the President discussing how the NSA can break into private homes to get documents) or for other criminal matters (politician taking bribes, adult trying to lure kids in a van, whatever).
Isn't there a line that protects both free speech and human dignity?
Given how small cameras and microphones have come, our freedom of speech has slammed into our rights to be safe and secure in our own homes, and lastly our own persons, our bodies.
Just like disallowing someone to yell fire in a theater, you are not actually imposing on free speech in a significant way, (I can still argue that it can be allowed, or that fires in theaters are a problem, etc), I don't see how allowing for human dignity will impose on free speech here.
I can see how a law will do that, but only if we try to be staunch and try to resist at all costs. This debate has been long in coming. We should participate and be instrumental in crafting something reasonable instead of letting a draconian law pass that merely uses a legitimate issue for the legislators' and their handlers' own ends.
What do we have to lose out on? A quick laugh at Star Wars kid where we got a few seconds of enjoyment at the cost of years of this kid's life and psyche, and other misfortunates like him? Where's the free speech in that?
