Olympic Security Chief Chris Allison said cuts in specialist police officers were already starting to bite. The Met Assistant Commissioner had asked chief constables to delay making cuts until after the Games, but warned police bosses will need to make “very difficult decisions” in the aftermath of London 2012. There were no security major incidents in the Olympics. This was partly due to more than 100 people being arrested in pre-emptive operations before the event, plus the deployment of extra troops.
