So if someone is making death threats, you think that is the job of an administrator?  So let me guess, if someone make a bomb threat, you think that is the job of the administrator to handle that too?  

The moment a threat or physical violence happens, it is the job and responsibility to call HPD.  Putting a TRO, issuing no trespasses on adults, and calling HPD is the responsible thing to do.

As for "No public high school in the state of Hawaii seems to be dealing with?"  I recall families waiting after football practice at Kahuku when they first hired Reggie Torres since he set higher academic standards.  

I recall last year when the boys basketball team boycotted playing for Coach Akina at Kahuku.  Parents went to school and made a lot of trouble.  And a mother even went onto the news to complain.

There's problems everywhere.  Last year so many parents complained during midseason at Punahou, the girls head coach resigned halfway through the season.  It's everywhere.
