Assuming the content is public, why would they need a subpoena?
I think we can tell what the RIAA thinks about that.
Being public doesn't mean publicly owned. It means publicly accessible... Like your local shopping mall.
If we have to play by those rules, LEO should too. Boo hoo if it's harder.
They haven't shown anything. They made a claim. We'll know what rules we have to play by if it comes to a court ruling.
