I completely agree with the thesis of the article; that outsourcing leads to inflexibility is performed by a staff that is not necessarily invested in the goals of the organisation. However, how does this apply to providing security for the Olympics, a once-off event that may not return to London for another 50 years? A city can't be expected to constantly maintain a police force capable of covering an event of this size.
