What we have right now (both in the US and the UK) is a set of overlapping (and sometimes conflicted) machineries of surveillance - in some/most instances, created without the oversight of 'democratic' mechanisms. There hasn't been a centralised move by those nation states to operate that.
The surveillance state that's being created seeks to remove the divisions between different components of those assemblages. The increasing normalisation of surveillance that's happened over the last 20 years will gather even more pace, and be justified on a number of spurious 'security' grounds, then 'efficiency' grounds.
They haven't said anything about intelligence provided to law enforcement.
Yep. And that's the whole reason 'parallel construction' exists at all in the U.S.... even when NSA has solid evidence of actual crimes being conducted, they will not burn intelligence sources & methods to allow for a court prosecution of the same.
So LE has to either find a way to independently arrive at the evidence that they know is there, or go without prosecuting criminals they know to be on the street.
Parallel construction is definitely distasteful but nor is it planting evidence.
I hadn't seen that particular take on it - I don't think we're particularly disagreeing, though, since that parallel construction is still a long way off 'NSA info appearing in police cruiser computers' - it'll happen, it's just not there yet...
