Can Trump supporters please provide some rationale for Trump’s behavior in El Paso?

Even if you assume all of the articles mentioning it are fake news, what do trump supporters think is happening in this image?

Really hoping to hear something that makes sense of a president giving a thumbs up in a photo op with a baby whose parents were violently gunned down.

(Not looking for a dog-piling by people who don’t like Trump. More curious about what the other side thinks of this.)
