I have the 5s and I don't intend on using the fingerprint scanner, because I believe there is no way that apple would not have built a backdoor to the chip so that they could access it if need be, however I also believe that since the lunch of the iphone 5s, CIA, FBI, NSA, MI6, MI5 etc would start asking apple to give them the codes, and if they don't say yes, they all will start trying to hack it, and it would take about month and they will all celebrate with a bottle of red wine and champain for their early Christmas present, which is everyone's finger print, which also empowers the Big Brother state. That's my theory so if on don't hear from me again or if this gets deleted you would know who did it lol.
