This really needs to be reiterated:
Riddle me this, May. Given that France not only operates a PRISM-like dragnet surveillance operation, but had the Charlie Hebdo murderers under surveillance until six months before the slaughter of the magazine’s cartoonists, would any of these new measures help stop terrorists in Blighty?
Of course, we all know the answer already: they wouldn’t. None of them would. This is a knee-jerk response to a problem which the government doesn’t know the answer to.
