I send them to this CNN page and tell them to look at the image in the story with the RV at the house. They like CNN.

Then I send them to this story to show the RV at the bombing site.
I ask them to look at the second side window. It is lower and smaller than the one at the site.
It works better, in my opinion, than sharing a meme because there is always the feeling that the meme was altered in some way. It also uses sites they like.
Not 100% positive on the validity of these pics, but showing the other side (matching sides) the vent is still different. This is fairly weird.

Definitely different if confirmed.
