The Los Angeles Unified School District has suspended high school teacher Greg Schiller because the science projects two of his students were working on looked dangerous. The two projects, which officials describe as "imitation weapons," are designed to shoot small projectiles. Schiller teaches several classes, including two Advance Placement courses. He'd been sending in lesson plans to a substitute, but school officials ordered him to stop because it violated his suspension. He was also coach of the fencing team, which can no longer practice or compete because no one is there to supervise them.
