Paul Andell argues that the death of George Floyd, a black man killed by a White police officer, the Black Lives Matter (BLM) highlights the current crisis in criminal and social justice. He notes that in the US public demonstrations were met with attempts, by the now defeated President Trump, deploying active duty troops under the 1807 Insurrection Act against the wishes of state and city authorities (Borger 2020). These events and others like them, he observes, have prompted questions across the globe about the role and accountability of state agencies in relation to black and working class communities. Aligned to this, further questions are raised about the kinds of knowledge that might be utilised to guide future policy and practice to improve the community safety of populations ‘at risk’ from ‘over-policing’.
