It is one of the pillars of the criminal justice system: a person who is accused of a crime is innocent until proven guilty. However, as everyone is well aware, that isn't necessarily how every criminal case is perceived. In this era of instant news and constant connection, everyone has an opinion, and thoughts become shared so quickly. If someone is accused of committing a crime, there is a good chance that the public at large will label that person guilty, even though he or she is innocent until the prosecution proves its case.
We say all of this because when someone is accused of a crime, there is so much on the line. Their reputation is on the line; their financial future is on the line; their professional livelihood is on the line; and most other aspects of the individual's life are on the line.
