Visiting The National Archives website is becoming more and more worthwhile: dispense with any mid 20th century notion that  might linger in your subconscious that it is little more than a catalogue! Michael Hopkins of Liverpool University has reviewed  what this new resource of Cabinet Papers offers  (or not) (click here). I will just point out that the Papers have been grouped by theme, one of which is Law, Liberty and society. 

Cabinet Papers online: Law Liberty & Society

Within this theme you can drill down through various links to discover Cabinet musings on – as an example- the changes in the law relating to murder and the abolition of the death penalty.
