On Monday 30th November, it emerged that "fast-time learning" from the Manchester Arena bombing attack had resulted in several changes in how UK counter-terrorism teams work.
The inquiry into the attack of 22 May 2017, which killed 22 people, heard that senior officers reviewed what happened five days later to learn from it and that their 21 recommendations had mostly been implemented.
A senior officer said that at the time, counter-terrorism focused on the nature, not the timing, of a threat. Lucy D'Orsi, deputy assistant commissioner with National Counter Terrorism Police, said she believed the security advice at the time was correct.
She said, "I think there should be a holistic focus on what the attack methodology is, which in this case was a person-borne IED (improved explosive device). There was no mention in the guidance of the specific terrorist threat of people leaving a concert, the inquiry heard.
According to Manchester Evening News DAC D'Orsi also said the legislation would be a 'seismic shift' in the way 'everyone approaches protective security', and be 'as ground-breaking to protective security as GDPR has been for data handling'.
"I think it is important that we move it forward as quickly as possible," she told the inquiry. This is about everybody playing their part. It reflects the learning from attacks and dreadful loss of life we have seen."
