Erm, the hitmen in Dubai didn't use the current ePassport
They used the old (but still valid) paper-passport.
So the fakers aren't even bothering with the current one, they're just making old ones because they're easier.
Surely somebody must realise that having 3 (possibly 4 - I forget when they changed) 'still valid' concurrent designs of passport makes them *less* secure, as staff are less likely to spot a fake when they're trying to match the document in front of them to multiple variants of 'real'.
It's not like cash, which circulates and therefore the banks can pretty easily 'swap-out' on the way through.
