I think TV has been a little bit irresponsible in how they portray these people because homicide detectives are not brooding, tortured souls who are stained with the stink of the city and who have blood on their hands. They are real, live people that are incredibly entertaining.
One eye-witness is of more weight than ten hearsays. Those who hear, speak of shat they have heard; whose who see, know beyond mistake. [Lat. , Pluris est oculatus testis unus, quam auriti decem. Qui audiunt, audita dicunt; qui vident, plane sciunt. ]
