to act or not to act

if someone lets a crim happen while their there and their watching they are just as guilty as the one whom commited the crim depending on what it is. Some people are caught in a certain scene at the wrong time like fights in school innocent people are near the fight and may be blamed or accused of having part in it. In this situation their nnot guilty. On the other hand their are robbers and murders who have a "sidekick" with them, the sidekick does not take part in the crim but they may help a little like driving the get away car.
