It could mean stepping in to keep a drunk woman from being whisked away from a party, calling over a bouncer or creating a noisy distraction at a bar, or just letting someone know that a rape joke isn't funny.
So-called bystander intervention tactics are emerging as a preferred strategy as colleges across the country look for ways to strengthen sexual assault prevention efforts.
It may seem like common sense to intervene — do something, say something — when a dangerous or potentially harmful situation presents itself. But stepping in, even subtly, can be tricky, particularly in unfamiliar situations, such as those arising at parties during freshman year.
Police say such involvement was lacking in two incidents in dormitories at Ramapo College in Mahwah, N.J., and William Paterson University in Wayne, N.J., last month that led to sexual assault charges.
In both cases, two men were charged with sexually assaulting a female student while three bystanders were accused by police of aiding and abetting the attack.
"It's fair to say that people watched the event occur and didn't intercede," Mahwah Police Chief James Batelli said of the Ramapo attack, in which another female student was among those charged with invasion of privacy and failure to render aid.
Ramapo President Peter Mercer said the lack of intervention was "distressing" amid the college's emphasis on teaching bystanders to step forward.
He has promised a full review of the school's policies and procedures on sexual violence, as has William Paterson University President Kathleen Waldron.
