To establish liability, the plaintiff offers into evidence the hospital record from her visit to the emergency room, in which she stated that the defendant failed to come to a complete stop at a red light when the plaintiff entered the crosswalk. The physician who made the entry still works at the hospital but has not been called to testify. If the defendant objects, should the court admit the evidence?
