What would you do if you saw bullies ganging up on an innocent kid or a couple fighting in the park -- the boyfriend on the verge of physically harming the woman? ABC News conducts a hidden camera s test to see what people do when confronted with ethical dilemmas that force them to act or not. Whether walking right by or getting involved in these scenarios, the reactions people have are fascinating. ABC News also takes the experiment further, looking at whether perception influences people's reactions. Will dressing the bullies tougher or changing the race of the fighting couple affect how people respond? Then: How will passengers handle a taxi driver who goes on an extensive racist rant filled with hateful ethnic slurs... will they tell him to stop, keep quiet, or maybe even join in? What some people think and openly say about race in America is surprising, including a woman who says all Arabs should be sent back to Ali Baba and a man who talks about using Mexicans and Puerto Ricans for target practice. Over the four-day experiment, some people will challenge the cab driver's racism, but will any of them tell him to stop or get out of the car?
