Can you imagine being accused of a crime when you are innocent? Let's pretend, for argument's sake, that you have been accused and let's call it murder. . . . .
The police come to your door, handcuff you, take you to jail and book you, all without any evidence that you may have actually committed the crime. Your next-door neighbor, who has hated you from the moment you moved in simply calls the police and informs them that you murdered his wife and they take his word for it, without any due process.
