Have you ever tinkered with electronics, or known a tinkerer? At this kid’s age, I spent plenty of time taking things apart, reassembling them, etc. The interesting part is the process, not what it looks like in the end.
And that’s not a “briefcase,” the photo is cropped to make it look bigger than it is. Look at the plug next to it for a sense of proportion. The case is not much bigger than a person’s hand.
I just placed the plug end of an extension cord on top of my hand to compare. Now, admittedly, I have a small hand, but still, I don’t believe his case is near the size of a hand...not even a man’s.
Taken together with the pic of the smiling, happy Muslims and the activist father, well...
