Assessing Evaluative Practice in Protective Security

With the potential implementation of Martyn’s Law in the UK, a national legislation focused on enhancing protective security measures in public and crowded spaces, there is an urgent need to understand effective evaluation in this field. Drawing insights from monitoring and evaluation practices in counter-terrorism, preventing and countering violent extremism and other fields, the article explores how the success of protective security interventions could be defined and measured across various dimensions. In doing so, it aims to contribute not only to the effective implementation of Martyn’s Law but also to the broader evidence base for future interventions in protective security.
