"As usual, the president assumed Americans are bigots before the contrary facts were in about Mohamed's suspicious-looking device and uncooperative behavior.
The principal, the school resource officer, and police questioned him, according to WFAA:
[O]fficers said Ahmed was being “passive aggressive” in his answers to their questions, and didn’t have a “reasonable answer” as to what he was doing with the case. Investigators said the student told them that it was just a clock that he was messing around with.
Irving police officer James McLellan remarked:
We attempted to question the juvenile about what it was and he would simply only say it was a clock. He didn’t offer any explanation as to what it was for, why he created this device, why he brought it to school.
Why this reticence? Why didn’t Ahmed tell McLellan what he so readily told the international media: that he loved building things and had brought the clock to school to show to an engineering teacher?"
