From the People's Republic of Cal-i-forn-eye-aye:
Cortines School's Greg Schiller was removed by L.A. Unified after two students' projects were deemed to resemble weapons.
Schiller was ordered to report daily to a district administrative office pending an investigation after two students turned in science-fair projects that were designed to shoot small projectiles.
One project used compressed air to propel a small object but it was not connected to a source of air pressure, so it could not have been fired.
L.A. Unified School District administrators have told Schiller that he was removed from his classroom for "supervising the building, research and development of imitation weapons," said union representative Roger Scott.
Eldest Daughter's science project last year was taking a blowtorch to various types of wood to measure the effect of density on combustion. Based on this article, I can only assume that its mere presence in an LA school would have caused pants-wetting hysteria and an eight hour lockdown.
Of course, there may be more to the story:
Schiller, 43, also was the teachers union representative on the campus and had been dealing with disagreements with administrators over updating the employment agreement under which the faculty works. His suspension, with pay, removed him from those discussions.
Makes me wonder if Mr. Schiller happened to have, you know, any doubleplus ungood ideas.
