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.
Although my wife just pointed out to me that they may be the same. They are pointed different directions. We're not comparing the same side.
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.
