If you were the only witness to a crime, would you come forward to report it?

Leader: Lilya.

Questions for discussion:

• Let us imagine: you▓re a witness of a theft in a big supermarket. You see another person stealing some thing that costs about 100 rubles. The theft hasn▓t notice you.  What would you do? In  case if the cost of a stolen thing was about 1000? About 10 000?
• Let us imagine that you▓re a witness of a murder, done at night near your house. You▓ don▓t know the person that was killed. What would you do?
• Let us consider the same situation but with an exception: you recognized a well-known journalist in the killed person.  How would you act in this situation?
