How about the "human rights" of journalists - and when did law firms and insurance companies acquire human rights? Furthermore, if it's all right to "taint" a popular newspaper with criminality, forcing it to close down, then why not not taint these other outfits too - and those mysterious "wealthy individuals"? It's obvious that the Metropolitan Police sees its role as pinching anti-censorship Murdoch hacks (and selling the pro-censorship Guardian information on who they plan to collar next), while Soca's job is to protect blue chips and Russian oligarchs.
I wonder if Soca employees have been taking hush money from them, like the Serious Fraud Office and the EU's anti-fraud squad do with other criminals? If "Britain's FBI" is as unaccountable to Parliament as it seems - just as Brussels' FBI, Europol, is unaccountable to the Strasburg one - then they might well be.
