Photoshopping Evidence in the Senate

The above image looks like a fairly typical refinery, right?

Well the image below is what Senator Boxer presented to the U.S. Senate in a fight against the Keystone XL Pipeline.

Isn't this ... kinda illegal? Not only does the photo below appear to be an obvious photoshop, but it is a poor photoshop at that. Clouds and stack smoke don't mix like that. Refineries do not create such smoke either!

Oh well... This is the most open and honest administration ever right?
