And those that weren't soon realised the true efficacy, as well as understanding there is actually no valid detection mechanism for detection in place at checkpoints (aided by the results from out-and-about searches).
I bet someone would have realised that within the 3 years they have been in use!
I believe there have been a lot of deadly explosions in Iraq ...

And if they were, the effect is not temporary, because the people saved still live. These bombers typically take 20 or 60 lives. If one was deterred, then that is worth hundreds of these wands.
The placebo effect itself
is temporary, regardless of how permanent the consequences are.
You are taking things in isolation. You have not accounted for those that did get through, and those who realised the minimal possibility of being caught (none beyond random chance).
Such phrases, like "
if it saves one life" are totally fallacious, possibly even wantonly disingenuous, if the causal factor that saved that one individual life had also resulted with the deaths of many others.

There indeed is,
if they're not at the expense of genuine treatments, such as "
often replacing physical inspections of vehicles"
At $60k a pop, that's a lot of sniffer dogs not bought.
$85m in Iraq alone is onehellof an expensive placebo!
Ammar Tuma, a member of the Iraqi Parliament’s Security and Defense Committee:
“
This company not only caused grave and massive losses of funds, but it has caused grave and massive losses of the lives of innocent Iraqi civilians, by the hundreds and thousands, from attacks that we thought we were immune to because we have this device,”
Since being deployed in 2008: "Despite the controversy, the device is still being used at checkpoints across Iraq." [Wiki]
Do you reckon the placebo effect is still going or long, long gone?
