However Police long ago started to switch to rigid handcuffs to stop people being able to move their hands and manipulate their way out : http://www.police-supplies.co.uk/handcuffs-keys-pouches/hand...

Since the indiegogo site will have been added to the 'criminal intelligence' database, every paranoid cop will take extra care.

You would be horrified at the number of snopes.com myths cops believe in, so something with the potential to be real will have them in a frenzy.

Expect lots of people to be beaten and tazer'd over the next week or two as a direct result of the hysteria this creates in cops all over the place believing people have a hidden super secret magic handcuff key.
