The public’s understanding of forensic DNA databases remains undertheorized and few empirical studies have been produced. This article aims to address this omission by exploring the answers to an open-ended question taken from an online questionnaire regarding the reasons for individuals’ voluntarily accepting or refusing to allow their DNA profile to be included in the Portuguese forensic DNA database. The analysis is undertaken from the perspective of biological citizenship and the simultaneous empowering and disempowering effects of surveillance. The results indicate (...) a pragmatic ethical framework that is linked to the cultural and emotional elements of altruism, resistance, stigma, and social representations of what is beneficial or harmful to the individual and to society. These subjectivities are anchored in commonplace images and metaphors for genetics, DNA, and forensic science that circulate in the messages transmitted by the media which pervade everyday life; hierarchies of trust in science and the justice system; and moral categories associated with the individual self-judgment in relation to crime, surveillance, and social order.

A number of public controversies have emerged around forensic DNA testing backlogs at crime laboratories in the United States. This study provides a first look at public responses to such backlogs, using a controversy in the state of Wisconsin as a case study. First, it builds on research about public understandings of DNA and the “CSI effect” to develop a theoretical framework. Next, it explores news coverage of the Wisconsin backlog. It then uses survey data to show that public understandings (...) of DNA, media use, and demographic factors were related to how closely respondents followed the story about the backlog and/or how much they supported increased spending on DNA testing at the crime lab. Self-reported understanding of DNA predicted following the backlog, whereas perceived reliability of DNA evidence predicted both following the backlog and support. Total television viewing was not related to either following the backlog or support, but watching crime television predicted following the backlog. Reading a newspaper and watching local TV news each predicted following the backlog; reading a newspaper also predicted support. These results suggest a number of theoretical insights into how members of the public may reason about and draw on media messages regarding DNA and DNA testing in responding to forensic DNA testing backlogs.
