Isn't this sort of thing inevitable? I mean, the more technology advances the easier and cheaper it becomes to build terrorist devices or WMDs. Therefore society, in order to protect itself, has to be vigilant about how the relevant knowledge disseminates. An analogy might be an individual guarding against suicidal thoughts.

More interesting to me is how to create mechanisms to control who gets access to the data and under what circumstances. I think in the UK we have a pretty bad record of local councils and other busybodies using snooping powers not intended for them.
