> Do they really want only a limited ability to access encrypted data? Again, I don't know. These arguments were all hashed out in the 1990's CALEA discussions. Assertions were made to "Trust Us", only limited use of the automated phone tapping requirements are envisioned. A few years later the CALEA technical requirements for tapping capacity were published. If I recall correctly (these are old bits), the capacity for the number of concurrent taps the FBI required for Manhattan was approximately the number of simultaneous off-hook phone lines expected for that size population. In other words, "capture it all". That's how "limited use" tends to go.
