It doesn’t even make much sense. Unless they’re hoping to catch body camera evidence of an employee using a phone to snap a picture of a prototype, what sort of leak would this possibly prevent? And really, would it be that hard to “accidentally” obscure the body camera for the 5 seconds it takes to snap such a photo anyway?
It certainly won’t stop you from calling, texting, or meeting a journalist in your free time to leak whatever information you want.
There’s probably much less to the story than this sensationalist headline suggests.
