Yeah, that was exactly my thought.

This wasn't confiscated because it remotely resembled a grenade - it does not. It 'resembles' very expensive cut crystal (expensive because the faceted cuts are made through a layer of colored glass to expose the clear core glass. There are no 'protuberances'; it bears as much resemblance to real grenade as a small ('baby pine') pineapple does.

Much more likely it was confiscated because the screener recognized the 'Jimmy Choo' name and high price tag. I wonder what they would have said if she'd offered to pour the perfume into another 'non-grenade-like' container.

Someone should go through PHX with a bottle like this with a hidden tracker. It would be interesting to follow it's progress and verify where it actually ends up.

Certainly demonstrates how few TSOs, military experience notwithstanding, have actually ever handled a real grenade - or even gotten close to one.
