Agreed. And the media has been silent about that, deliberately silent. Ahmed has admitted knowing his device would look suspicious. I wonder if he made it in response to 9/11, the anniversary of which was on Friday. Perhaps that made him angry, so he came up with the clock/bomb to bring in Monday to restore his sense of pride.
Not when you’re looking at a circuit board and a digital read out. I’m not sure how a school teacher would know the difference between clock boy’s Radio Shack clock and a bomb mechanism shown in the movies.
