It's called capitralism, mate. It ain't perfect, but it works most of the time. I think what is much worse is the way the media and politicians jumped on this tragedy to further their own agenda. Now that people are pushing back, they are coming up with bullshit like how now Obama shoots all the time. He's supposed to be our friend now. pffffft. I do however agree that some of the Photoshops were in poor taste, I suspect the whole idea is a play on the fact that the original was probably just as fake as the picture of Obama in the situation room when Bin Laden was killed.
Edit: I've done some reading and it appears that one of Obama's advisors basically challenged people to Photoshop the photo, and they did in spades. Some in bad taste, some pretty funny.
