Drive-By Shooting Suspect Remotely Wipes iPhone X, Catches Extra Charges (appleinsider.com)
schwit1 shares a report from Apple Insider: A woman from Schenectady, N.Y. accused of being the driver in a shooting used Apple's remote wipe feature to destroy evidence on her iPhone X that might have been related to the event. The iPhone was seized as evidence in the case, but police say that shortly after she triggered the remote wipe, an option available via Find My iPhone in iCloud. Normally the tool is intended for people with lost or stolen devices. The suspected driver, Juelle Grant, was arrested on November 2nd and charged with two counts of tampering with physical evidence, and one count of hindering prosecution. As Apple Insider notes, only one of the tampering counts is connected to the iPhone.
How about a one-way drop box on police cars that's a Faraday cage, grounded to the car's chassis with a lock that only management can open. Should prevent phones from being wiped, and preserve the chain of evidence -- if a body cam shows the phone being dropped into the secure box and the box is only opened in the presence of two people, it would reduce the risk of accusations of evidence tampering. Better yet, design the box to be sent directly to a trustworthy lab equipped with a Faraday cage where they can work on the phone. (i.e. PD can only put the phone in, they can't unlock it at all).
