The entrance to the radiofrequency isolation chamber, near the middle of the Lefkowitz Building in lower Manhattan, looks like an artifact from the Apollo program, shielded by two airtight, metallic doors that are specially designed to block electromagnetic waves. Inside the room, against one wall, are dozens of Apple iPhones and iPads in various states of disrepair. Some have cracked glass fronts or broken cases. Others look like they’ve been fished out of a smoldering campfire. Of course, the devices are not there to be fixed. They are evidence confiscated during the commission of alleged crimes.

Welcome to ground zero in the encryption battle between state and federal law enforcement officials on one side, and trillion-dollar tech giants Apple and Google on the other.

Fascinating if a little (lot?) scary.
