Most of it seems like bureaucrats trying to get access to information after they have obtained warrants. It all seems a lot more boring and a lot less cloak and dagger if you actually dredge through the bill here:
https://www.gov.uk/government/uploads/system/uploads/attachm...
The document mentions encryption four times and backdoors no times. One of those times is to say that the bill does not change anything about encryption that isn't already in law under this bill, RIPA: https://en.wikipedia.org/wiki/Regulation_of_Investigatory_Po...
Really actually more scared of RIPA (which is already law) than this:
"In October 2014, it was revealed that RIPA had been used by UK police forces to obtain information about journalists' sources in at least two cases. These related to the so-called Plebgate inquiry and the prosecution of Chris Huhne for perversion of the course of justice."
It's amazing to me that the first two cases are absolute abuses of power; I thought we were still being told that these laws were to stop terrorists and paedophiles, not find out journalists sources...
