"Hackett promised the ICO he would make sure encryption was used on all mobile and portable devices, that ..."
...he would personally pay a huge fine from his own wages ??
After all, his huge wages are because of the responsibility he has, and in this he has failed. 30 years ago it may have been excusable that he didn't know about the risks of data loss, but after so many articles even in the normal press, there is no excuse.
People that are in these positions of responsibility, earning top money should personally pay for the mistakes in management made below them. In this way, they will have a better incentive to do their job properly. (carrot AND stick)
