I understand the technology- but my qualms is with the process and the time-lines mentioned with regards to the interception. Why cannot the sanction process be 24 x 7? Also, why should a sanction of such a critical action like reading someone's email go unreviewed for two months?

We are in 2009 and not in 1984, right?

I feel this has misuse written all over it. And unfortunately, I feel GPG is not really the answer here for 99% of the email users (unless gmail and yahoo decide to turn it on by default).
