I remember doing something similar in college level intro to communications class, except it was a hostage situation and the hostage takers allowed you to pick certain people that they would let go. I don't think they mentioned race though,

There lived a woman named Abigail who was in love with a man named Gregory. Gregory lived on the shore of a river. Abigail lived on the opposite shore of the same river. The river that separated the two lovers was teeming with dangerous alligators. Abigail wanted to cross the river to be with Gregory. Unfortunately, the bridge had been washed out by a heavy flood the previous week. So she went to ask Sinbad, a riverboat captain, to take her across. He said he would be glad to if she would consent to go to bed with him prior to the voyage. She promptly refused and went to a friend named Ivan to explain her plight. Ivan did not want to get involved at all in the situation. Abigail felt her only alternative was to accept Sinbad’s terms. Sinbad fulfilled his promise to Abigail and delivered her into the arms of Gregory.
When Abigail told Gregory about her amorous escapade in order to cross the river, Gregory cast her aside with disdain. Heartsick and rejected, Abigail turned to Slug with her tale of woe. Slug, feeling compassion for Abigail, sought out Gregory and beat him brutally. Abigail was overjoyed at the sight of Gregory getting his due. As the sun set on the horizon, people heard Abigail laughing at Gregory.
