@gungasnake,
1. Pointing out that the German police were armed is sensationalism. French police are routinely armed, Spanish police, Italian police, need I go on?
2. "The right to home schooling is a human right" No it isn't. It is the responsibility of parents to ensure that their children receive a decent education, as judged by national standards of that country. If the parents cannot show that this is being provided, the state ensures that the CHILDREN'S human right to a decent education is respected.
Unqualified parents may or may not be able to teach their children properly. The state cannot sit by and end up with a family of teenage kids who are unable to read and write, but can just about fashion clay or paint a tree.
3. A state education is not just about cramming knowledge into brains. Most western countries make some attempt to develop a fully "rounded" young adult by the end of their schooling. This is partly achieved by children mixing and socialising with other children from other families.
Activities such as debating, public speaking and team sports help develop a child both physically and mentally, and is much better achieved in a school environment.
4. What the hell has this German issue got to do with the American home schooling busybodies?
