> Maybe he's being downvoted because the so-called facts he's basing his suspicion on can be easily disproven

Which of the 3 points have been dis-proven?

Also take into concideration that -

1. The kid had a metal box containing PCBs and probably large components, all tide together around with a wire, and it was making beeping noises in class.

2. The school body and school district is almost 90% non-white, with the majority being "brown".

re. 1: His claim that it is "highly unlikely" that a home-made clock would look like a bomb needs some citation. Unless your definition of "looks like a bomb" is "anything with PCBs and wires, stuck in some kind of box", at which point I would argue that any home-made clock will look like a bomb.

re. 2: He's asking the father to provide an image of something that was confiscated by the police or school administration. Furthermore, the first video with the boy contained a fairly detailed description of the clock, and the second video even contains an image of the box (or at least a similar box).

re. 3: Well, he provided an alternative explanation for that himself.
