You'll frequently hear law enforcement complain that it can't break the full-drive encryption in newer smartphone operating systems, but how often do the police run into that problem, really? Thanks to a US Senate Judiciary Committee hearing, you now have a better idea. The Manhattan District Attorney's office has revealed that, out of the 92 cases where an iPhone withiOS 8 has been involved so far, the cops have been locked out 74 times. District Attorney Cyrus Vance portrays this as proof that officers need backdoors or other forms of guaranteed access, noting that there's at least one case (in Illinois) where evidence from a victim's iPhone led to a conviction. Police shouldn't simply be told that there's "nothing [they] can do," he says.
