Here we go again, smart (LOL) politicians want to force Facebook, Google et-al to help them break encryption. Whilst their argument in favour is commendable, it's also plain stupid. First of all it is accepted by those who understand technology and mathematics that it's not possible for the companies to break the encryption of messages they handle for their users, stupid politicians (yes including Mrs Brandis) want to ignore two important realities: if government and messaging companies find a way to do it, then criminals and nasty people will too; second, government agencies have been known to occasionally (excuse the gross understatement) have crooked coppers and officials abuse their facilities for a variety of reasons.
Imagine, if Faceook technicians work out a way to enable police to access your WhatsApp messages, then what do you think the technician will say if some criminal syndicate offers him 10 million dollars to come over and provide the solution? Or, if some criminal warns the technicians he will kills each member of his wider family unless he cooperates.
The idea is stupid. Malcom and Mrs Brandis are being typical politicians (doh!). They ignore the reality that despite police in the UK having the law on their side insofar as access to private data is concerned, they cannot make the companies decrypt encryption.
