What message is Reuters sending when Biden is “targeted”?

A few days ago, Reuters published in its gallery a set of pictures of Biden giving a speech on Feb. 4, and a few of them were very strange. The photo caption reads, “President Biden speaks to congressional staffers as seen through a camera on Feb. 4.” The photographer was Tom Brenner, and many people’s first thought when they saw the photos was that the shooter was aiming at Biden! Why was Biden photographed in such a specific light? Is there a message there? If the photos were scrap, why did Reuters put them in the gallery for users to download?
