We need a level of government to deal with conflicts and unsafe environments.
But when it comes to children, the government seems to strike out more often than get on base.
One of the best topics for discussion received so far is from arthurus on this thread who suggested school counselors, but I guess that would depend on the school.
The other best topic came in an email to consider allowing relatives, aunts, uncles, grandparents to have temporary custody while the conflict gets investigated.
How old is the kid? A relationship with the school counselor should be developed prior to relating problems.
See if they might be trusted.
Get involved with a strong Christian Church prior to relating problems as they be assisting when you go to court. There may be cops counselors in the Church that. May be available for advice etc.
Getting close to school teachers would be desired especially one who could help when you go to court.
