In a perfect world, this guy would have had the iPhone 5s, instead of 5c model. That's the model with the biometric fingerprint sensor for unlocking. The FBI could have chopped his finger off and used it to unlock the device. I saw that in an episode of "24" and it worked for Jack Bauer. Then again, if the guy had a brain in his head, he would have disabled this feature before the terror attack.
My wife was shocked that Apple would not capitulate to help the government. I had to explain that I have bank information, passwords and other content that I cannot afford the bad guys to get. If you make a back door, you've opened Pandora's box. Not only will the government expect this every time they need help, the hackers will also have an opening. Tim Cook understands that one of the reasons Apple is so successful is the public trusts them to protect their content. When you look at the pros and cons of this, you begin to realize that, more than likely, it would be far more dangerous to comply with the government than anything that they might find on this device.
