“…This piece builds on the many critiques of the hegemonic “radicalization” discourse, which highlight a lack of scientific rigor underpinning key concepts, and the discursive construction of pre‐crime risk (Ahmad & Monaghan, 2019; Baker‐Beall, Heath‐Kelly, & Jarvis, 2014; Githens‐Mazer & Lambert, 2010; Heath‐Kelly, 2013; Kundnani, 2009; Martin, 2014, 2018; Silva, 2018). While the definitional ambiguity surrounding terrorism preemption has been widely documented (Elshimi, 2017; Elshimi, 2017; Lowe, 2017; Richards, 2011; Sedgwick, 2010), little empirical work has been undertaken to explore how contested terms like “radicalization,” “extremism,” and “de‐radicalization” are navigated in practice through Prevent's operation. Some research on the practitioning of the Channel program does exist, including that of Elshimi (2017), Thornton and Bouhana (2017), Spalek and Davies (2012), and Weeks (2017, 2018).…”
