A girl was placed in a science class discussion group with students who were not speaking english. She asked to be put in another group so that she could actually figure out what was going on, and the teacher had a conniption. A week later, due to the teacher's complaint, the girl is arrested for racism.
There are so many elements here to lay blame on I don't even know where to begin. The school? The teacher? The police? The laws?
The bottom line is that things are looking bad in Britain. If this were an isolated incident I'd brush it off, but stories like this are coming out of the UK at ever increasing rates. Britain may be one of the first societies to self-implode due to insanity.
