You are absolutely right about the optics (and the blinkin' lights). The forensic expert made the same point—unintended drama is still drama. I definitely didn't aim for this (just wanted to demo the hardware), but once the process started, I had to respect the thoroughness. Their protocols are no joke.
The grilling by US security types was a "feature" of crossing any US controlled border space for a number of years after this: https://news.ycombinator.com/item?id=46597539 in 1998.
You spend one month at ground zero for 11 nuclear tests that caught most of the five eyes by suprise and that's all they ever seem to ask about forever.
It is fascinating to see the evolution of the 'threat signature,' though. You were flagged for proximity to literal nuclear physics in 1998; I was flagged for a vibe-coded prototype that just looked like physics in 2026.
I have a sinking feeling that, like you, I've just unlocked the 'secondary screening' achievement for the next decade. I’ll take the permanent Swiss police record over the Five Eyes watchlist any day. You win.
Seperately again some nice people in Finland gave us some really nice SAKO TRG's and spotting scopes in return for being the fastest to find some drums of waste they hid in a forest.
My father (still alive) is a few years older than M.J., they grew up together, being from the same part of the same state .. so it was handy having them going to bat for us when faecal matter contacted propellers ( https://en.wikipedia.org/wiki/Michael_Jeffery ).
If it looks like Osama bin Laden attending a War on Terror summit ... they'll wave it right through.

Not an especially wise move if unintended, and a precarious risk if intended fpr the drama.
I'm thinking my personal best time getting grilled over a suspected security issue runs to 36 hours or so .. hard to tell in retrospect, the US TLA bods do like their blinken lights and screeching music to mess with peoples internal clocks.
