I think this is an issue that needs to be totally vetted because there are two sides, and I've posted opinions of these two sides. One an argument of logic and opinion and the other an argument of logic and reality based experience and facts. For the most part I have a large degree of respect for Levin's veiws and opinions. In this case - he's missed the boat. First, here's his take on this issue.
Now after hearing Mark Levin's views here's the view of someone, John McAfee, who actaully knows and understands the technology and the dangers as to what the FBI is demanding. Including the idea a federal judeg can order a company to create softwear that doens't exist.
