National counter-terrorism police had to rely on updates from Twitter for nearly two hours after the Manchester Arena attack, the inquiry has heard.
The SO15 Reserve, a 24-hour operations centre for national counter-terrorism operations, was still having to rely on Twitter for information at 12.13am, nearly two hours after the attack.
The evidence is being given by this man.
"I think they must have been listening to the force radio or heard something happen in that area and he had contacted his wife and said, 'Don't go to sleep because it looks like something's happening',"
Great! The terrorist response is reliant on gossip from a friend of a friend...
Mr Basu said social media could be a help but added: "It's a massive hindrance when there's so much of it that it takes experienced detectives and analysts a long time to go through the material and that obviously could divert resources."
You aren't kidding! So...why did you have to rely on it?
The force duty officer at Greater Manchester Police, who was supposed to notify SO15, was said to be "overloaded" and had to get a junior officer to answer his phone.
Perhaps recruiting police officers on the basis of their skin colour, religion or gender rather than their ability to deal with pressure isn't a winning strategy, eh, GMP?
Or maybe they should, in any future terrorist attack, just tell callers to ask the terrorist what he wants and give it to him?
