I feel like programmers model the law as a programming language, while it only works like that in very limited contexts.
They said Raspberry PI, but the spirit of the rule is "electronic looking thing that we can't immediately determine the function of". You could probably show up with an unpopulated PCB and get turned away because it's green.

If this expands beyond a single event, I look forward to the inevitable lawsuit, and wish those seeking to oppose such suppression the best of luck.
