We know for a fact that the English teacher thought it looked like a bomb when she confiscated it.
*beep*beep*beep*
"Who is making that noise?"
"Sorry, ma'am."
<teacher looks at device in backpack>
"Young man, you put that bomb on my desk this instant and return to your seat! There will be no further disruptions in my classroom, is that understood?"
"Yes, ma'am".
The teacher didn't think it was a bomb. She did not report a bomb in her classroom, the school was not evacuated, and the bomb squad was not called in to deal with the device.
Apparently she thought it was something that violated school policy, but we haven't heard from her what policy she was thinking about. She might have been thinking about a "no weapons or dangerous items in school" policy, or she might have been thinking about a policy that all electronic devices must be kept in lockers until the end of the day. She might have suspected shenanigans were imminent, and called the Principal to warn him.
She might be sensible and responsible educator, or she might be a rabid bigot who sees little budding terrorists whenever she looks at Muslim children. Or she might be a completely different personality type. We don't know because we haven't heard her story yet.)
