There is a way in but it's a lot of work. They have to create a new weird custom build of an OS with modifications and try to ensure it only works on a specific device (and that the code that makes it work on one specific device and not others can't be circumvented). To do it once? Sure. For San Bernadino terroists? Sure. But there are hordes of prosecutors across the country who have already reported in that they have stacks of warrants for iPhones ready to go, requesting a special build, engineer time, and a complicated procedure for every single one the moment the precedent is established. So the real question is: Can the FBI compel apple to create a "department of helping the FBI hack into iPhones?"
