Spontaneous public response to a marauding knife attack on the London underground: Sociality, coordination and a repertoire of actions evidenced by CCTV footage.

Across a range of recent terrorist attacks in the United Kingdom, the question of how crowds behave in confined public space is an important concern. Classical theoretical assumptions are that human behaviour in such contexts is relatively uniform, self-interested and pathological. We contest these assumptions by reporting on a study of public response to a marauding knife attack that occurred on London's underground rail network in 2015.
