- 未知题型 Thirty-two people watched Kitty' Genovese being killed right beneath their windows. She was their neighbor. Yet none of them helped her. Not one even called the policE.Was this gunman cruelty? Was it lack of feeling about one's fellow man?'Not so,' say scientists John Barley and Bib FatanE.These men went beyond the headlines to probe the masons why people didn't act.

Is he having a heart attack? Is he in a coma(昏迷) from diabetes(糖尿病)? Or is he about to sleep off a drunk? Is the smoke coming into the room from a leak in the air conditioning? Is it 'steam pipes'?

Scientists found that the people were emotional, they sweated, they had trembling hands. They felt the other person's troublE.But they did not act. They were in a group.
