Apple has to create a "waiting list" for police requests regarding the decryption of seized iPhone. ATF allows Apple to bypass its own software security rules to help law enforcement agency.
Apple's latest response to Police is "Wait". It happened because Apple is getting so many requests from police to unlock the seized iPhone that it has to release a waiting list. Now police has to wait at least for 7 weeks for the completion of the request.
ATF is the Federal Bureau of Alcohol, Tobacco, Firearms and Explosives. It needs police help in Kentucky iPhone 4S case. According to the CNET report, the ATF agent Rob Maynard has made a search warrant in last summer "to locate a local, state, or federal law enforcement agency with the forensic capabilities to unlock" an iPhone 4S. Yet he did not get any positive response as "police agencies did not have the forensic capability."
As a result, ATF approaches Apple for decryption help last year. Now the seized iPhone needed to get unlocked. U.S. judge of district court, Karen Caldwell, gave a recent statement about the situation. She said that when an ATF correspondent "contacted Apple to obtain assistance in unlocking the device, ATF was placed on a waiting list by the company."
Now police have to wait at least 7 weeks so that there request could come in process. While there is no time limit about the completion of process.
