This is exactly the response to this tragedy that I was fearing in the UK. What the article fails to mention is that France passed their own sweeping surveillance law earlier this year [1], and it clearly failed to stop this attack from happening. That isn't to say that increased surveillance never aids in intercepting terrorism, but to sell it as a golden bullet is highly disingenuous. Now is precisely the wrong time to be making rash decisions and passing reactionary legislation which will have serious ramifications for privacy and cyber-security for years to come.
