Here's the way I look at this:  

A parent becomes irate over a science grade, or a science curriculum's lack of including intelligent design.  Get police to guard the science class?  Cancel the science class?

A Band parent becomes irate over choice of songs played, or what instrument a kid is given.  Have police buzz the band practice?  Cancel band for the year?

A parent becomes irate over the choice of discipline handed out by the Vice Principal for whatever violation charged.  Have the police stand by?  Cancel school for the year?

A football parent becomes irate over treatment of their kid.  Or, the plays called.  Have police stand by and buzz practices?  Cancel the season for the year?

All present precisely the same parental concerns and emotions.  

We KNOW how Kaiser handles irate parents (police and cancellation).

How does ANY educational situation get to the point where parents become so irate?  Without administrative intervention?  To at least separate the parents . . .
