In many places, the photographs of smokers' diseased lungs, mouths, tongues, etc. have been forced onto the packaging of cigarettes. There was a commercial which aired recently showing the many disgusting results of smoking cigarettes. It was so disgusting I had to change the channel rather than watch the whole thing.
Maybe we can push the U.S. Congress to force gun assault weapon and assault ammo manufacturers to place photos of the mutilated bodies of 1st graders on the packaging for these products. It at least might get the attention of the NRA/ survivalist / "gun enthusiasts" who are complaining the government is trying to take their guns. It does not interfere with the 2nd Amendment in any way, and would be a good reminder of what assault weapons and assualt ammo can do to the human body, especially a child's body. It could change the mind of those with a conscience which outweighs their unfounded fears.
(note: I found far uglier photos to post with this blog, but decided to go with a more gentle but reminding vision.)
