Honestly, just pack something with a USB port, and no descriptor. No labels, no nothing. Hell, make it out of a little hobby box container and put a port on it. Done.
Some dumb ass will plug it in to see what it is.
Remember, police have a maximum intelligence limit for hiring, or so its rumored, and if you’ve dealt with many cops, well… seems pretty fair.
Intelligent people ask questions. Fascism doesn’t like people asking questions.
