There's been much mirth and merriment over the "butt bomb" used by a terrorist in an assassination (ass-ass-ination?) attempt on a Saudi prince.
However, as some have observed, this guy got past the checkpoints and security inspections meant to keep the prince safe.
And we have to recall the scene in The Dark Knight, in which the screenwriter suggested an even more nefarious hidden bomb.
So here is the question: how long before a woman undergoes a Caesarean section and has the baby and her uterus replaced with a fairly sizeable bomb, with a mechanical trigger (the kind she can set off by punching herself in the stomach)? With no electrical or electronic components and little or no metal in its construction, it would be undetectable, assuming that any airport screener would even think to check a pregnant woman that closely.
