Spies should be able to monitor all online messaging, says David Cameron - Telegraph:
He added: “I have a very simple principle which will be the heart of the new
legislation that will be necessary. In our country, do we want to allow a
means of communication between people which even in extremis, with a
signed warrant from the home secretary personally, that we cannot read? “Up
until now, governments have said: ‘No, we must not’.
“That is why in extremis it has been possible to read someone’s letter, to
listen to someone's telephone, to mobile communications.
“But the question remains: are we going to allow a means of communications
which it simply isn’t possible to read. My answer to that question is: ‘No
we must not’.
“The first duty of any government is to keep our country and people safe. The
attacks in Paris demonstrated the scale of the threat that we face and the
need to have robust powers through our intelligence and security agencies in
order to keep our people safe.
