All Government Organisations and representatives (with the notable exception of the honourable ladies and gentlemen of the House of Lords) appear unable or unwilling to take this issue by the scruff of the neck. The Information Commission in particular has appeared totally toothless even allowing time for them to get up to speed with a new technology.
When BT next run a trial, which this time cannot be covert (the watchers are being watched), I suspect the issues will reach Court for a decision.
The judiciary will decide if BT can monitor and profile its customers without their explicit consent.
