You shouldn't send an email from a computer that's associated with you if you don't want it to be tracked back to you. You don't want to hack the power plant from your house if you don't want them to follow the trail back and see your IP address.

No one would argue that it's in the United States' interest to have independent knowledge of the plans and intentions of foreign countries. But we need to think about where to draw the line on these kind of operations so we're not always attacking our allies, the people we trust, the people we need to rely on, and to have them in turn rely on us.

You have ceded the concept of your own rights. You've converted them into something you get as a revocable privilege from the government, something that can be abrogated at its convenience. And that has diminished the measure of liberty within a society.

People have to be free to investigate computer security. People have to be free to look for the vulnerabilities and create proof of concept code to show that they are true vulnerabilities in order for us to secure our systems.

We have to decide why terrorism is a new threat. There has always been terrorism.

If the United States is promoting the development of exploits, of vulnerabilities, of insecurity in this critical infrastructure, and we're not fixing it when we find it, instead we put it on the shelf so we can use it the next time we want to launch an attack against some foreign country. We're leaving ourselves at risk.

I think the public still isn't aware of the frequency with which the cyber-attacks, as they're being called in the press, are being used by governments around the world, not just the US.
