In the United States the greatest threat to freedom
does not come from the US Government 3 letter agencies, it comes from the private sector. The MPAA is a much greater threat to freedom than the NSA, the NFL is a much greater threat to freedom than the CIA, The RIAA is a much greater threat to freedom than the FBI, etc. Once Americans figure this out, they will no longer tolerate these kind of laws and try to impose them on the rest of the world. Libertarians get this dead wrong!
Ever heard of the saying "The pen is mightier than the sword". This saying is from the 19th century that is very applicable today; however the pen today has been replaced by the computer, the smart phone, the tablet etc, while the sword has been replaced by the gun, nuclear weapons, chemical weapons etc.
So why is for example the MPAA such a threat. In their obsession with attempting to prevent "copyright infringement" they are actively taking away control of the pen away from citizens with DRM. patent monopolies, anti-circumvention laws etc. The DMCA was a perfect example. The failed attempt at SOPA was another. In addition the United States is actively exporting this kind of repression via trade agreements around the world at the behest of the MPAA and its tyrannical allies. One of the reasons for using trade agreements is to get around the checks and balances in the US Congress. That is for example how the DMCA got passed in the first place.
If Americans really want to use their guns to preserve freedom they need to take all their DRM infected devices to the firing range and use them for target practice. There is no law in the United States against shooting a locked cell phone to smithereens in the firing range and buying an unlocked one instead.
This has to be one of the best application of firearms in the preservation of freedom:
