Re: Risk vs benefit
I would compare it to roads. About 8 people will die today on UK roads....
Sorry, but you have that wrong by almost a factor of two. 4.7 people will die on the roads statistically today. The annual total is 1713.
Would we rather give up all privacy and have no terrorist attacks, or put up with a few attacks and keep all of our encryption
Assuming it were an all or nothing choice, you'd probably find that the absence of encryption caused more deaths than actual terrorists. An absence of any encryption would lead to a surge in corporate espionage and a commensurate surge in job losses due to business closure (everyone else will still be encrypted, just not UK data), and correlated surge in suicides. 58 terror deaths since 2000, with NHS figures suggesting that 2008-2010 around 1000 suicides were due to job loss.
