I have no time for UKIP.
I was just pointing out you were wrong to assume that they had no policy for a post-EU world. Even they're not that politically naive.
Obviously Im limited by the data available but Id bet money that the historic trend is upwards since 1979.
As for your argument about anti-terrorism and war laws, you're missing the nature of the SIs. Go and have a look at them. The thousands of SIs are generally petty interferring bits of legislation. There are alledgedly some more substantive un-debated laws hidden amongs the tide of SIs too. Anti Terror laws were debated. War wasnt. The post 9/11 world didnt lead to a need for lots of new bits of legislation, it was approached with just one or two large Acts. It didnt lead to an unavoidable increase in the number of laws - the "socialist" love of centrist dictat did that.
