The onus is on women who are sexually assaulted, as always. The difference now may be that we see far more women respond with immediacy and report to police and hospitals, while taking copious notes and making note of any potential witnesses. The social campaigns are doing much to eradicate the sense of shame among women and rightly shifting it to these men. More women will feel power to do all that's necessary to have these men face the strongest possible evidence against them.
