There are many reasons people "look the other way," fear, feeling powerless do to anything, and a lot of the time, at least in everyday examples, it's simply that they think someone else will do something.

SEATTLE -- The shocking video of a pregnant woman being kicked and punched on a Metro bus is prompting officials to increase security.
The video footage, which was first seen on KOMO News, is shocking, even for the most seasoned deputies. Five girls jumped the victim in the back of the bus. The camera captured every blow.
"I saw my whole face was like bleeding, and I was like, 'Oh, my goodness!' And it's dripping and stuff," said the victim, Jessica.
The girls were seen grabbing Jessica's MP3 player out of her hand. Jessica is seen pleading with the girls to stop, telling them she's pregnant.
"One of them kept kicking me in the back and stuff. And you know, I didn't want anything to happen," she said.
But the fists keep flying, and Jessica says not a single passenger tried to help.
Sheriff Sue Rahr can't believe nobody on board called 911. When the bus driver eventually did call 911, the attack was already over.
"I'm shocked," said Rahr. "Frankly I think people were so shocked that it took them a while to process what was happening."
