I prefer leaving things to the market as much as possible.

Although cyber attacks have caused billions of dollars in damage and affected the lives of millions, few if any can be characterised as acts of terrorism.

Cyber terrorism could also become more attractive as the real and virtual worlds become more closely coupled, with automobiles, appliances, and other devices attached to the Internet.

While many hackers have the knowledge, skills, and tools to attack computer systems, they generally lack the motivation to cause violence or severe economic or social harm.

Further, the next generation of terrorists will grow up in a digital world, with ever more powerful and easy-to-use hacking tools at their disposal.

I don't have a particular recommendation other than that we base decisions on as much hard data as possible. We need to carefully look at all the options and all their ramifications in making our decisions.

We have never really had absolute privacy with our records or our electronic communications - government agencies have always been able to gain access with appropriate court orders.
