:By "sued" I think you mean "charged."  "Sue" to most English-speakers refers to civil actions (one citizen sues another) and not criminal charges (government tries and punishes for a crime).  But your point is well taken.  I would say physical child abuse tends to be the first subject that pops into most people's head when they hear "child abuse,"  but the section is quite lacking in general.  The linked article physical abuse from that section is also not only very short, but very broad, referring to abuse of adults as well.  I will see what I can do to add more information on the general subject.  I have several textbooks that should make good objective sources.
