These are ridiculous scenarios to try and optimize for. A smartphone feature isn't going to save someone from an abusive spouse or a serial killer, and if it does, it'll be an exceptional situation.

There was a youtuber who got kidnapped in Haiti a while back, and his kidnappers demanded to search the photo gallery on his phone for something. So what he did was delete the pictures, but not empty the trash, hoping they wouldn't know about that feature. They didnt, and he got away with it. Did Apple envision a kidnapping scenario when they were designing that feature? Probably not. Is there a design lesson that can be taken from that situation? Also probably not, because it just as easily could have gone the other way.
