Watch Those Math Teachers!

At Heathrow Air­port today, an indi­vid­ual, lat­er dis­cov­ered to be a pub­lic school teacher, was arrest­ed try­ing to board a flight while in pos­ses­sion of a com­pass, a pro­trac­tor, and a graph­i­cal calculator.

Author­i­ties believe he is a mem­ber of the noto­ri­ous al-Gebra move­ment. He is being charged with car­ry­ing weapons of math instruction.
