I agree with all but your last paragraph.  If there are situations where 2 kids of different races do the same thing and only one is punished, then it would be very rare and should be addressed legally or by moving your kid to another school.  But I think the problem stems from broken homes where a father is absent and children don't know how to behave or disciplined early so they know not to act up in schools.  In some cases it might be a mental health issue or abusive household.  Those need to be addressed through intervention or special needs not assuming it's all racial profiling.    I'm not sure what you mean by social promotion.  The only promotion the school should be concerned with is merit promotion.  If the child does the work and understands the material he/she are promoted to the next level.  Kids with learning disabilities, and emotional problems should have those needs met through special needs classes or medical help.
