Back when the Snowden revelations came out the UK was worse than the US when it came to civil society surveillance and unlike the US, the Government there just retroactivelly legalized all that their NSA-equivalent (the GCHQ) did with no restrictions.
Oh, and the UK Press has a censorship mechanism called D-Notices.
In this domain the UK is already worse than the US, probably because the idea that the populus should know their place and be led by “their betters” is pretty old in Britain and, at least for the elites, the thinking about the relation between power and the people never significativelly evolved away from the original thinking in Absolute Monarchies, since the political and power structures there are still anchored on a Monarchy.
If by that you mean that some out of touch MPs can be easily swindled by members of the security apparatus working together with other MPs and higher level politicians who are smart enough to know what they’re doing, I don’t disagree with that.
What is less likely is that a majority of British MPs, repeatedly and over the course of 2 decades, have been deceived like that.
Maybe I’m wrong, but most British MPs don’t come out as stupid (though some definitely do) - incompetent at anything but salesmanship and power-games, crooked, greedy, ethics-free, unprincipled salesmen types and people driven by objectives which do not at all match what they state, sure most of them come out as that, stupid, not most.
I mean, your point would make a lot of sense if this was some kind of one-off event rather than a repeating pattern of measure after measure increasing surveillance of Civil Society, for the last 2 decades, and if Civil Society (or at least the Media) had been silent about it or even supportive of it, but as things stand the theory that a majority of MPs are stupid as an explanation for this bill passing Parliament really stretches the laws of probability.
As the saying goes: “You can deceive some people all of the time or all people some of the time but you can’t deceive all people all of the time”.
PS: I accept that I might be wrong. I just don’t think that given the Historical track record the odds favor the “they’ve been swindled” (a majority of them and again on a subject that has been steadily going in just this direction and with not so long ago exposés on the press of how previous legislation has been abused for surveillance) explanation over the explanation that at least the ones in leadership positions acted with full awareness and possibly the active intention and purpose of crafting and passing a bill that expands Civil Society Surveillance in Britain.
