“The patio was lit only with candles and moonlight, so aides used the camera lights on their phones to help the stone-faced Trump and Abe read through the documents,” Liptak writes. In DeAgazio’s first photo, you can see a phone flashlight being used in that way.
 
 

Why is this important? Mobile phones have flashlights, yes — and cameras, microphones and Internet connectivity. When Edward Snowden was meeting with reporters in Hong Kong at the moment he was leaking the material he’d stolen from the NSA, he famously asked that they place their phones in the refrigerator — blocking any radio signals in the event that the visitors’ phones had been hacked. This was considered the most secure way of ensuring that the phones couldn’t be used as wiretaps, even more secure than removing the battery. Phones — especially phones with their flashes turned on for improved visibility — are portable television satellite trucks and, if compromised, can be used to get a great deal of information about what’s happening nearby, unless precautions are taken.
