Actually if Im not mistaken thir is right in that the UK did indeed change several of its security policies many times through out its entire history depending on which administration was in charge and what had been happening at the time conserning how long people could be detained and what type of questioning one could use, and whom one could hold and why and how much force could be used in different situations for prevention or reciprocity up to and including even what levels of observation and freedoms were allowed over the general public its movments and such etc.

I wonder if Norway will be changing their own again soon?
