Should parents be made aware of teachers who have plead guilty to assault and battery against a student?

Please note that Mr. Zangkas is presently working full-time at Derby Middle School.  What is your opinion on whether or not you would want your child to be in his class?  Should parents be made aware of teachers who have plead guilty of assault and battery against a student? 

From Rob Lawrence's blog "Schools, Politics, and Common Sense April 2008
The Birmingham School Board is forced to take back into full time employment a teacher (Michael Zangkas) that has, 1) plead guilty to contributing to the delinquency of minors (multiple students 13 years of age), 2) plead guilty to assault and battery against a student (13 years of age), and 3) in the course of the above events said to the student that he assaulted that “Next time I’ll drown you.” Not to put a fine point on it, but that sounds a threat against someones life.

In light of these facts the Teacher Tenure Commission has set a new bar for teacher misconduct - apparently a teacher actually has to kill a student before the tenure commission heads the recommendations of a school board (the board unanimously had voted 7-0 to terminate Mr. Zangkas for his actions)...
