Airport security is massively excessive when you look at the
actual threat, compare the chances of being killed by a terrorist blowing up an aircraft(Btw your plane is more likely to crash than be blown up by a terrorist.) to being killed in a car crash for example. You are massively more likely to be killed in a car crash, but does road safety receive the budget of national security? Of course not! Because the government wants to scare the population, because fear enables governments, big business etc to perform actions and justify them using the fear created.
The example above(I sware the post now seems to have been edited, though it doesn't say it was :confused ) shows how the population has had this mock "fear" installed upon them. One person 3D Prints an ATM facia and the imediate reaction is to call for the police to be informed of anyone ordering a 3D Printed facia.
People need to take personal responsibility and stop looking to the state to look after them. From a safety point of view I'd personally be more worried about crossing the road to the ATM than I would be about my card details being stolen.
I agree with what Youknowwho4eva said above, if someone ordered a 3D Print of an item of police equipment it would be sensible to inquire as to why they need it. Considering you can buy your own handcuffs legally, it would be suspicious to order a key for police issue cuffs.
