OREANDA-NEWS. March 22, 2016. First, the US government needs to get a court to compel Apple to make an end run around iPhone security. Then it may have to figure what to do if key engineers quit the company.

The Justice Department has been pressing Apple to create custom software that would give it access to the contents of an iPhone 5C tied to Syed Farook, one of the two shooters in the San Bernardino, California, massacre in December, in which 14 people were killed. Apple has been fiercely resisting, arguing that the result would be a "backdoor" that would undermine privacy and security in all iPhones.

A court hearing on Tuesday will be a key step in what's likely to be a long road still toward resolving the legal dispute.

If the government eventually prevails, it may then run into another significant roadblock: the potential departure of Apple engineers skilled in the ways of encryption, the technology that scrambles documents so that they can be read only by authorized people or devices.

Apple employees have already discussed what they would do if Apple is ordered to comply, The New York Times reported Friday, citing interviews with than a half-dozen current and former Apple workers. Some employees said they would "balk" at the work, but others have indicated that they might quit their jobs rather than weaken the very software they built.
