If a hypothesis was made, don't make the classic mistake of accepting all confirmatory evidence and dismissing all contradictory evidence. Keep an open mind and constantly reexamine earlier assumptions and conclusions on the basis of evidence found later. A wrongful conviction is a triple injustice. If you convict the wrong person of an actual crime, then an innocent person goes to prison, the actual criminal remains at large and free to harm others, and public confidence in the legal system will be undermined. Study the mistakes of others so you don't repeat them.
Prosecutors are human.
Like everyone else, they can make mistakes. By studying the known mistakes of other prosecutors in cases like the Paul Ingram case and others, you can reduce the risk of repeating those mistakes yourself. Remember, only you can prevent wrongful convictions. As a prosecutor, it is not your job to try every case you are presented with. You also have a responsibility to exercise good judgement and choose not to indict in cases where evidence is lacking.
