In a quick read
What I expect to see: How apple enables police to invade our privacy
What I actually see: 3 apps that digitize paperwork and help police do thier job on iPhone, and CarPlay
Conclusion: It looks like WWDC but for the cops. It is nothing wrong to use iPhone or whatever phone to make work more efficient. It is a tool after all.
It is still better be on the err side and leave no trace they can use aginst.
