- "Your Honor, ladies and gentlemen of the jury, for you to understand what it is I'm about to tell you today, you need to do something. I need you to believe in the impossible. As children, we're taught that the police are there to protect us, to serve. We're told that our tax dollars go toward training them to be the champions of the city. But for some of us, it still seems impossible that a police investigator, one of Central City's finest, could betray that trust. And even worse, under the guise of upholding the law to commit the most heinous act that on person can carry out against another. But that is exactly what Barry Allen did. Now, the prosecution will prove beyond any doubt that he stood among us a wolf in sheep's clothing. But here's the thing. Barry Allen wears a mask, used his connection to the law, his experience as a police investigator, especially as a crime scene technician, to stalk a beloved professor and husband and murder Clifford DeVoe in cold blood."
