Newsflash!

Bombs really aren't all that common. TSA is a waste of money and energy.

"My laser smelled drugs on you."
No, it'll never take off.

Study after study has shown that drug and bomb sniffing dogs are little better than chance, hundreds of times more likely to show a false positive instead of a false negative, and cued by their handlers more than anything.  This leads to the dogs being extremely racist pointing out Hispanics and Blacks resulting in many more false positives than with white suspects.

good news for sharks

Good, One day we'll be able to walk straight onto planes because we'll be scanned by laser and metal detectors in the terminal without a security queue.

Although in such minute amounts, what are the odds that someone can accrue tiny bits of explosive without knowing? I'd hate to miss a plane because I sat next to a chemistry professor on the train to the airport.

So they just have a button the handler presses to make the thing beep, instead of the subtle cues they have to train the dog to look for?

Teeny tiny sharks.

Nor terrorists  sneaking onto airlines, apparently.

But they'll spend billions on this anyway despite the obviously cheaper, proven technology that a simple dog offers because TSA. And your money.

When our resident TSA defenders get online, please feel free to tell us about all the terrorists you've caught in the last ten years. Hint: dumbass Americans who forget they have a gun with them are not terrorists.

Probably pretty good.

I've suggested to my friends that they should rub a little bit of gunpowder on their clothes before they fly so that the puffer thingy goes off.

Then just explain that you were cleaning your guns, or went to the range.

If enough people do it, the false positives would be great enough that they'd either raise the alarm limit, or just wave people on.

None of them are willing to go through the hassle of it, though.

Dogs aren't that proven.

When I was in the Army, they'd occasionally run the dogs through looking for drugs.  One alerted on my room-mates locker.  Apparently, it was interested in his dirty socks.

/No drugs whatsoever.

I haven't seen one of those puffer things in at least 5 years and I take at least 20 flights a year.

My rolling bag set off that residue swap thingee once. It sucked. They unpacked and unfolded everything in my bag. Almost missed the flight.

A mini-laser? It was bound to happen eventually.

One less reason to justify the continued association with dogs.

I guess those poor dogs will just have to stay home and sleep on the couch. Those poor, poor bomb-sniffing dogs...

But I thought 9-1-1 changed everything?

I thought gas spectroscopy was handling this.

George! There's an explosive 2,342 miles away! In a workbench drawer!

The smell master identified it as Trinitrotoluene

Look at what the TSA actually does.  Is it about weapons?  The WTMD would catch them.  The pornoscopes are completely incapable of seeing a properly-hidden weapon.  There is a guy who demonstrated taking a metal box through the pornoscopes without being caught.  There's no fakery, just exploiting a basic flaw in the system.

Is it about bombs?  The  blasting cap can be hidden the same as a weapon.  A statistical model of how they work (the researchers couldn't get access to a real machine to test it on) shows that a properly hidden bomb also won't be recognized for what it is.  (Note: The same researchers that pointed out the flaw that lets you slip metal through--and that flaw has been put to the test and found to be real.)

If it's not either of these cases maybe it's something else?  What does TSA actually "accomplish"?  Drug busts and drug money busts.  The pornoscanner will find money or drugs, something the WTMD will not.  Are they really that incompetent or is their real mission not their stated mission?  I think the latter--it's an attempt to bypass the 4th.

Mostly people in such a situation know they were around explosives.  However, I read one report where nobody involved realized the problem:  The detector at the airport said her diaper bag had C4.  A careful search turns up no bomb.  She has nothing to do with explosives.  Eventually they figured it out:  Her husband packed the bag for her.  He did EOD at the army base.

The puffers had maintenance issues, they were pulled.  All that's around now is the machine they swab your stuff with and put the test strip in the machine.

My wife tripped that once (she had an object in her bag that couldn't be resolved by x-ray.)  They looked and looked, they seemed almost disappointed when we didn't give a hoot about how long it took.  (We had a very long connect, if they had taken a couple of hours it wouldn't have mattered.)

I would vote for any candidate (R or D) that used disbanding the TSA as part of their platform.

What happened to the scanner tha can tell what kind of wine is in the bottle by its molecular components without even opening it?
