Wayne Coyne is that idiot holding up the TSA queue

The presence of the TSA at airports in the US might do very little to stop terrorists, but they do perform a diligent job of stopping gun nuts taking their nutty weapons onto planes - the last week in October, for example, they stopped 38 loaded guns being taken on board by twitchy fellow travellers. And a throwing star. And a bunch of grenades.

Yes, a bunch of grenades. While you're juggling a sudoku book and an iPod, there are people who put grenades in their carry-ons. Perhaps they don't intend to use them. Perhaps they plan to show their displeasure if the beef meal has run out by the time the steward makes it to their seat.

There's an awful lot wrong with the TSA, but stopping the sort of people who are deluded enough to take live or fake weapons into a tiny plane is a really useful byproduct.

I mean, what sort of person would try to take a grenade onto a plane?

What's that? Wayne Coyne, you say?

Yes, Coyne held up a security queue - causing people to miss flights and lose money. Because he had a grenade in his carry-on.

Coyne can explain, though:

The Embryonic leader described the airport officials as "very nice," and admitted some fault, but Coyne wouldn't accept full responsibility for inconveniencing his fellow travelers (even though he did tweet that apology the same day as this mishap). "I would agree that it was stupid of me, but I don't feel wholly responsible if people missed their flights," he said. "I'm not making the rules. It's not illegal for me to have that grenade with me."

The grenade was a fake, and Coyne claims he "forgot" he had it with him. I guess it's possible - only last June I forgot I hadn't put my bottle of water in the bin as I moved towards the front of ORD. I mean, who wouldn't forget they'd put a grenade in their bags, right?

It's just disappointing that Coyne won't accept that he was in the wrong, and it was his fault. Because despite what he says, realistic explosives are banned from flights, either as carry-on or in baggage.

Mainly because the only way to tell if a grenade is a real grenade or just an uncanny lookalike is to set it off.

Mainly because if someone stands up on your plane demanding that Miss Congeniality II is shown as the in-flight movie, it's pretty hard to tell if they're waving round a genuine grenade or (as Coyne had) "a non-explodable grenade painted gold".

Yes, Coyne is convinced because it had been painted gold, that somehow showed that it wasn't a threat to the flight.

It's true that Coyne doesn't make the rules. It's true the TSA might have some odd rules and some awkward moments applying them, but not taking things that look like they could blow up a plane onto a plane is a pretty good rule, and really, if you don't want to follow that sort of rule, Wayne, stick to the bus in future.
