Teacher cert---does it avoid child abuse?

Oh! I just read the most insightful post about teacher certification and child abuse. I had to spread it around! Her first point I thought was extremely well put in stating that the schools and government in general are answerable to the public, not the other way around. Then she goes on to talk about the correlation (or lack of such) of teacher certification and child abuse. It seems like folks who talk about the need of teacher certifications follow it up almost immediately with the concern that homeschooling is a way to hide child abuse. I have seen very few homeschoolers address both concerns in one address, and this writer does a beautiful job of it IMO.
