Japanese man arrested for carrying hand grenades at Hawaii airport

No average airline staff could know if the grenades were inert or not.

For an M61, if the pin is pulled, safety clip removed and the hand toggle is fully open or missing, then it is inert.

However,

Cannot be shipped outside of the United States, FPO or APO addresses or to the state of California in accordance with California Penal Code 12020.) CAN'T BE SHIPPED INTERNATIONALLY, TO CANADA, ETC. IF YOU ORDER THESE AND DO NOT MEET THE SHIPPING CRITERIA WE WILL TAKE THEM OFF YOUR ORDER AND REFUND YOU.

Let me check the TSA prohibited items list:

https://www.tsa.gov/travel/security-screening/whatcanibring/items/hand-grenades says NO, not in checked or hand carried luggage.

 The final decision rests with the TSA officer on whether an item is allowed through the checkpoint.

Of course, Japanese laws probably prohibit them.

Within the US, looks like the only way to transport them is by informal ground shipping - i.e. not UPS, USPS, FedEx, but by getting someone to drive it.

I think airlines X Ray even checked baggage.

There's "stupid " and there's possible terror intent.

No average airline staff could know if the grenades were inert or not.

People rob banks with fake pistols , for example.

idiot

Guess I'm the only one who thinks this is completely blown out of proportion. He took too paperweights to the airport for a flight home. What's wrong with that? These things aren't hard to find.

In hindsight, perhaps he should have shipped them? IDK.

Tell me the guy actually thought he could get this past TSA screening. He could have put them in his check in luggage and unless J customs looked through his bags (which I have never seen with a J passport holder) he would have his souvenirs at home.

if he really had and intent of a terrorist attack that is troublesome

As the article says, the grenades were inert, which makes them basically just souvenirs or toys.

Still, staff in a plane or airport have no way of knowing what’s a toy and what isn’t. If he were to pull these out and threaten, people would have to take him seriously. Put these in checked luggage, and I doubt there would have been a problem. Try to carry these through security, as this guy did, and it’s time to do some explaining to the police.

Probably this guy bouth them as "surveniers".... if not, if he really had and intent of a terrorist attack that is troublesome... either case very stupid, you should know that having that kind of thing will get you arrested, even if the US size was ok with it (it is deffinatevly not), bringing that stuff to Japan is a big no-no.

Also concerning that someone sold or gave handgranades to a turist...
