From 'need to share' to 'need to care': information aggregation and the need to care about how surveillance technologies are used for counter-terrorism

Imagine this scenario: Anne, a soldier on deployment at a military base in a foreign conflict, meets a friend, Barry, for their morning jog. She posts, before and after, selfies of herself and Barry, updates her ‘JoggerLogger’ social media account with details of her run, and then heads to the shower. In doing this, Anne has put counter-terrorism operations at risk. The underpinning problem is that Anne has not treated potentially important information with due care. This chapter argues that individuals need to be careful with their personal information and that of others, even if that information is publicly available and/or relatively innocuous. Ultimately, I suggest that we need to shift our attitude to personal information from ‘need to share’ to ‘need to care’.
