Hypothetical #6 A psychiatrist is testifying at a murder trial in support of a criminal defendant. The doctor states: "After reviewing the reports submitted by the two court-appointed psychiatrists, it is my professional opinion that the defendant suffers from a severe depression with suicidal tendencies. It is my opinion that the defendant was in an unstable frame of mind when he killed the victim." The prosecution objects stating this defense witness needs first hand knowledge of the facts in order to testify as an expert.

(2) What would the defense need to show in order for the judge to allow the witness to testify as an expert in this case? Hypothetical #7
