I haven't heard anyone claim he invented a clock, but I have seen people setting up a strawman argument knocking down the non-existent claim he invented a clock.
The mainstream narrative is he took electronic clock parts from one case and put them into another case, and this was so innocuous that the jackboot overreaction of his school Principal and the cops was a national disgrace.
Mainstream narrative: he was arrested and suspended because the school and the cops thought it was a bomb after the English teacher innocently happened to stumble across it after the clock inadvertently and through no fault of Ahmed's started beeping. The reason for this is because everyone involved in every step of the process is Islamophobic, and Ahmed is a Muslim. Zero tolerance might be a factor, but the Muslim thing is what pushed it over the edge.
Yeah, that pretty much sums it up, but you forgot the part about the cop saying "I knew it was you" or words to that effect. How could the cop have known any such thing, when Ahmed hadn't been in any sort of trouble before? Was it the kid's name that aroused the cop's suspicion? It certainly couldn't have been due to any priors on his record, because there weren't any.
Fact: Ahmed admits he knew some might view it as suspicious or a threat, and yet chose this particular case to put the clock into anyway, and claims to have taken actions to mitigate the possibility of a perceived threat.
Fact: He intentionally plugged in the device and set the alarm to go off in the middle of class,
Did he plug it in, or are you speculating? The reports I read said the clock was in the kid's backpack when the alarm went off.
which got the teachers attention. The cops therefore may have reasonable grounds to investigate a "bomb hoax" scenario. It's not completely out of the question given this fact pattern, and warrants follow-up.
Fact: The three day suspension was almost certainly for making it go off in the middle of class as a result of what the school thought were actions intended to make people suspicious, which isn't a completely implausible viewpoint given the facts.
Fact: What you just posted is not a fact.
Also, fact: the kid is 14 years old, and can be expected to act with all the foresight, thoughtfulness, and maturity typically exhibited by boys his age. I'm sure his clock wasn't the only electronic device to ever accidently start making noise in English class.
Very reasonable speculation: Had the scenario been different, where the teacher saw something sticking out of his bag and asked what it was, and he said, "this is an alarm clock I took out of its case put in a pencil box, want to see?" "Sure...Oh my, why did you bring that to school?" "I brought it to show Mr. X, the engineering teacher.", the outcome almost certainly would've been different.
The only thing I can't explain are the handcuffs. Unreasonable under any interpretation of the facts (he was not violent or out of control, and did not pose any physical threat). It is probably this stupid action of the cops that made the case become so big in the first place, with the viral photo and everything.
Yes, it was.
