There has been a lot of commentary on the prank in which some DJs from 2DAY-FM managed to be put through to the hospital where the Duchess of Cambridge was recovering from severe morning sickness.

Sadly the nurse who answered the call and transferred it to another nurse has now killed herself, presumably over the guilt and shame caused by this incident.

There have been the predictable "blood on your hands" outraged tweets and emails. But I think this, from Britain's Daily Mirror puts some perspective:

But according to Princess Diana’s former bodyguard Ken Wharfe, if established protocol had been followed, the DJs would never have got through to Kate’s ward.

Mr Wharfe said: “When I was protecting Diana, the first thing we did when we arrived at a hotel or anywhere else was to isolate the switchboard.

“You tell the staff to put any calls through to the detective there. The royals never ring in to hospitals.

"If anyone needed to speak to Kate they would ring the officer outside her room. All this should have been explained to hospital staff but clearly it wasn’t.

"The procedures that should have been followed have been around for years.”

I know we all hate procedures, policies and protocols, but sometimes they save lives.
