A sexual assault scenario staged on a London subway train and caught on video is creating a stir online. The makers of the video set out to perform a social experiment aimed at raising awareness about sexual assault and harassment on public transportation, a major problem in London. The exchange between the actor and actress, though it took a few moments to register with onlookers, really got the attention of riders on the train once they realized what was unfolding. In fact, the situation escalated to a point that the people making the video thought was a possibility, but likely didn’t expect would materialize. When you watch the video, which already has more than 725,000 views on YouTube since being uploaded earlier this week, you’ll realize why.
