The Open Rights Group have reported on the Lords Constitution Committee report on surveillance and privacy. This is a monster document, which can be read here: Constitution Committee - Second Report. Surveillance: Citizens and the State. It's a big document, and it perhaps easier to digest via the ORG synopsis, and as the ORG say, "Those with nothing to hide can still have a great deal to fear".
The RIPA sections are interesting (Committee report section; ORG interpretation), in light of pretty clear local council abuses of RIPA ro spot fly-tippers etc.
