Why would a terrorist want to plant a Bluetooth device on someone else's bag when all it would accomplish is a minor delay of one flight and would result in a prison sentence after security camera review??
Why stop at one bag for one flight?
> would result in a prison sentence
That doesn’t seem like a significant deterrent here.
Remember: Kim Jong-Un’s brother was not killed directly by North Korean goons. They hired two women they convinced they were working on a prank show to spray him with the poisons.
You’d do something like that.
