He has recently been involved in a study of the August 2011 English riots. An innovative project which aimed to undertake high quality social research at a speed and in a way that maximised opportunities for influencing public debate, Reading the Riots was run jointly with The Guardian, and its initial results were published in their entirety in the newspaper. Currently, together with Professors David Downes and Paul Rock, Tim is currently engaged in researching and writing of an Official History of Post-war Criminal Justice.
