I'll start by describing my jury duty experience.
So I got selected for jury duty, and it turned out to be a murder trial. The trial went something like this...
Part I: What Happened
Three black teenagers exit a nightclub. They are friends. A fourth black teenager approaches them, shoots the one in the middle, then speeds off on a bicycle.
Coincidentally, an off-duty homocide cop, on his way home, witnesses the entire thing while driving by in his car. He jumps out of the car and starts chasing the murderer but isn't able to catch him. So he returns to help tend to the victim and to radio for some on-duty uniformed cops to come handle the scene.
The uniformed cops arrive and they are dealing with the scene, when the off-duty cop notices a guy in the crowd who looks suspiciously like the assailant. He not only resembled the killer, but was wearing identical clothing, sweating profusely and breathing heavily as if he had recently been in a chase of some kind. The off-duty homocide cop knew from experience that murderers often return to the scene of the crime, so he thought that it might be a good idea to detain this guy and question him. So he tells the uniformed cops to "Catch that guy!"
What followed was a 40 minute chase wherein the suspect led these police officers down dark streets, and through back alleys. He even kicked in some poor old lady's back door and ran through her house and out her front door. The cops only caught him with aid from the helicopter.
They take him to the station where a scientific test was performed on his hands. The test showed, with 99% accuracy, that the suspect had fired a gun within the past hour. Needless to say, he is held for some time.
Later, for some reason that I do not remember, the cops let him go.
Still later, a superior officer asked about this case and learned that the guy was released! So he orders the officers to immediately re-apprehend the guy.
So they go out and arrest a young black teenager.
