Britain has a national obsession with "preserving stuff for the nation"
Well, well. I think Ledswinger has put his finger on the surveillance obsession.
The government merely wants to preserve all the mindless chatter of the entire country and all the swapped 'genital passport photos' for the enrichment of future generations....
How many decades 'til the entire country is one huge museum, crusting over with antiquated IT 'cause the government can't put new systems in place without blowing the project and antique goverment that's (roughly) 70% tradition and furry ceremony, 20% pomp and privilege and 10% ineptitude.
