What were the two competing issues the California Supreme Court had to figure out how to balance in the Tarasoff cases (one issue was “pitted against” the other)?  How did they balance those two competing issues (i.e., which was given more weight in the Tarasoff decisions)?

How did the 1976 Tarasoff decision differ from the 1974 Tarasoff decision?

What made the Mike Tyson evaluation so unique?

There was one clinical psychologist as part of the team of five evaluating Mike Tyson from the Massachusetts General Hospital.  The clinical psychologist used three tools as part of his assessment.  But it seems to me that the psychologist should’ve used another specific kind of measure that wasn’t included in the three measures he used.  What kind of measure did the psychologist not use that he should’ve used?  List a specific tool or two that you think he should’ve used, and explain why he should’ve used the tool(s).
