So, the political aspects first. The Scottish Parliament is broadcast live on TV here and politicians in Scotland are no different from those in England. So labour slags off SNP, SNP slags off the Tories and as there are hardly any elected Tories in Scotland, they slag off everybody else. The Liberal Democrats run with the wind. I think you get my drift.
I agree with Phil's comments about politics and politicians and I would re-quote whoever said it but the worst thing about politics is politicians, or that old joke, "how do you know when politician is lying?", "when they open their mouth".
As someone who works within the Criminal Justice System I would love to be in the position to post here that the Scottish Judicial System differs greatly from that in England, and is inherently superior. Alas the end result, I fear is very similar to England.
Certainly as a starting point our legal systems differ greatly, with the English legal system forming legislation that is more prescriptive than Scotland where we also have "common law" that you don't have in England so much. Common law is not set in legislation but includes precedent and case law that has grown over the years and is in part derived from Roman law. In that sense, common law is dynamic or organic, developing as it does in response to legal, political and societal changes.
However when it comes to criminal trials and civil disputes the legal process is very adversarial, with the emphasis on both sides scoring points against each other rather than an attempt to seek "justice" which as Phil says could be an attempt to discover the truth by an inquisitorial process.
It is also the case that some legislation is UK wide and does not have a separate "tartan" version. The examples that come to mind right away would be something like the Data Protection Act 1998. It is also true to say that European Law is having a homogenising effect on law across the UK, The Human Rights Act being an example.
