Disruptive crowd behaviour back in the news again!
This time it's journalists saying it's a thing.
But crowd safety professionals say 'The overwhelming majority of events take place safely & securely, with no disruption, but those stories rarely make the news.”

Swearing, booing and spitting: is crowd behaviour out of control?
There was dismay after Rory McIlroy’s wife was hit by a beer at the Ryder Cup. But have crowds always been badly behaved, or is antisocial behaviour getting worse?

Barely an hour ago, Palestinian journalist Anas Al-Sharif warned us all:
“If this madness doesn’t end, Gaza will be reduced to ruins, its people’s voices silenced, their faces erased — and history will remember you as silent witnesses to a genocide you chose not to stop.”
Israel just killed him.

New from Drury & Vestergren. The chapter synthesises decades of research on how participation in collective action transforms people, challenges the field’s focus on predictors, and calls for methods to trace these transformations. It also highlights prefiguration as a key future research direction.
'Reading historical examples of person change in collective action, one is struck by the profound sense of revelation, & the significant downstream consequences, in terms of future activities, relationships, &life choices.'
