Not related to the point of the video but the OSA is a terrible legislation which basically protects leaders and various controllers from accountability for their actions and the OSA is one of the reasons Tony Blair is still a free man. The problem is the OSA can apply for decades, basically as long as they want, until the truth of their actions is revealed but by that time very few take notice so accountability never happens. It's nothing to do with National Security but more "Cover our arses when we too break the laws". Ultimately you have to question the legitimacy of the OSA when we already know Governments are no longer nationalised.
