Just for clarity: The anti-terrorism squad did not yank him out of class; the anti-terrorism squad took an interest in the Facebook post and contacted the school.
Thames Valley Police sent a “schools officer” (whatever that means) to the school, and Wishart was asked by the school secretary to leave the classroom to talk to the officer.
So don’t anyone go getting visions of tooled-up kevlar-vested armed police bursting into the class-room.
