Security expert Bruce Schneier weighs in. This is a guy who absolutely knows what he’s talking about:
The FBI’s demands are specific to one phone, which might make its request seem reasonable if you don’t consider the technological implications: Authorities have the phone in their lawful possession, and they only need help seeing what’s on it in case it can tell them something about how the San Bernardino shooters operated. But the hacked software the court and the FBI wants Apple to provide would be general. It would work on any phone of the same model. It has to.
Make no mistake; this is what a backdoor looks like. This is an existing vulnerability in iPhone security that could be exploited by anyone.
What the FBI wants to do would make us less secure, even though it’s in the name of keeping us safe from harm. Powerful governments, democratic and totalitarian alike, want access to user data for both law enforcement and social control. We cannot build a backdoor that only works for a particular type of government, or only in the presence of a particular court order.
Either everyone gets security or no one does.
