There has been much talk lately about the internet being a fundamental right. That basically means that the government has to go through much more hoops to take it away from you, even in the case of emergencies.
As a fun exercise of contrast:
A. Finland has declared the internet as a fundamental right.
and
B. The United States is trying to pass the Protecting Cyberspace as a National Asset Act, which essentially allows the president to “turn off” the internet in the face of perceived threat. This is why it has been dubbed the “internet kill switch”.
There is an obvious irony in turning off the internet out of fear for a terrorist cyber attack.
