Destroy the Evidence



Our hero, or another good character, has come into possession of some evidence relating to a crime. However, instead of turning this evidence over to the proper authorities, the hero destroys (or withholds/hides) the evidence.

Why? Well, there's a number of reasons. For instance:
 * The evidence could incriminate someone else who the hero likes and doesn't want to see punished.
 * The evidence, if made public, will ruin the victim's life (or the life of someone involved in the crime).
 * The hero is being blackmailed by the Big Bad or an associate.
 * The hero would be incriminated by the evidence.
 * The evidence contains information which would exonerate another villain who is on trial for another crime.
 * The evidence, if involving a dead person, might cast a bad light on their memory—and the hero was a good friend/relative/lover of the dead person.
 * The evidence is entirely worthless—it's too late to act.
 * The hero wants to punish the bad guy himself.
 * While the evidence could get the bad guy put away or otherwise punished, it would cause scandals and create chaos for a lot of people, some who may be entirely innocent.
 * The evidence would reveal an ugly truth about a past event that the public perceives as a good thing, and the hero wants the event to stay a good thing.
 * The criminal committed the crime for a good reason, and in retrospect the hero agrees that the act was justified.
 * The crime involved the murder of someone who was a truly terrible person, and the hero doesn't want the evidence revealed, since it would result in someone going to prison for something he doesn't think of as a crime.
 * The hero is currently on the run or at least not on good terms with the local authorities, so he can't give the evidence to them without being captured/killed/arrested.
 * The hero is actually the villain.
 * The hero believes that the criminal is genuinely repentant and need not be punished further.

Whatever good intentions the hero may have had, destroying the evidence will probably have bad results — a villain could walk free (or somebody could Give the Villain a Hero's Funeral), for instance. May result in a What the Hell, Hero?.
