So Amber Rudd, the home secretary, went on the Andrew Marr show on Sunday to say that WhatsApp, the globe-conquering messaging service, should hand over the final messages of Khalid Masood, the Westminster terror attacker.
She said organisations like WhatsApp shouldn't provide a "secret place for terrorists to hide". She also used the phrase "necessary hashtags". It didn't go down very well.

10. It reminded more than one person of something from the political satire The Thick of It.
11. Lots of people were keeping Rudd informed of their movements, just in case.
