James b. Comey spoke yesterday and regretted that the industry is increasingly selling equipment such as smartphones and tablets with full encryption of content, which makes some searches and gathering of evidence in case of offenses.
The FBI Director said after the release of the iPhone 6, where one of the most heralded features is precisely data encryption, although many Android-powered equipment also has the place from 2011.
 The authorities advocate the use of a 'backdoor' in all equipment, where you can enter in the event of suspicion of crime and duly mandated for this purpose. The big problem is that this 'door' can always be used by criminals to undermine the privacy and security of users.

The Atlantic explains that the FBI director fears that there are devices that may be inaccessible to the authorities.
 Devices that encrypt the contents by default can hide evidence and clues of crimes such as robberies, kidnappings and other.
Comey explains that what's going on in the technology now, with encryption by default, is the same as selling cars whose trunk cannot be opened by the authorities never even with court order. However, the existence of this type of equipment helps maintain users ' content safe from criminals and even help to avoid cases in which the authorities are carrying out surveillance operations of surreptitiously, as illustrated by Edward Snowden, in the complaints of NSA practices.
