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.

I favor strategies that encourage industry to include some sort of key recovery capability in their systems which would also address user requirements for access.

The concern is over what will happen as strong encryption becomes commonplace with all digital communications and stored data. Right now the use of encryption isn't all that widespread, but that state of affairs is expected to change rapidly.

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.

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

Systems are complex, so controlling an attack and achieving a desired level of damage may be harder than using physical weapons.

While the vast majority of hackers may be disinclined towards violence, it would only take a few to turn cyber terrorism into reality.
