There's the old saying, "the camera never lies", which I've never understood because it often does.
With any single photo you are capturing a fraction of a second (to avoid smart****s, I'm going to point out shutter speeds, but obviously I'm talking about every day, general photography) and you're taking away all context.
Number of times you see photos in tabloids of people who are supposed to be angry, sad, annoyed, doesn't care, etc, but it's just one photo of probably hundreds taken and chosen to fit that newspaper's agenda.
There's plenty of sticks to beat Trump with, but with your added context Jon, doesn't seem this is one of them.
