The US tried SOPA and PIPA in recent months and while most people think they are gone, defeated, the fact is, the danger is still present, just delayed.
Those US laws are supposed to stop piracy and protect intellectual property, don't believe it. If they are passed they will be the thin edge that signals the end of internet freedoms. Who knows what will follow, what interests need to be "protected" by government fiat?
One thing that may disappear is the kind of thing displayed in Robert Higgs' speech last month at the Mises Institute. Higgs pulls no punches, and tells it like he sees it. It's almost an hour long, but well worth your time.
