They seem to be upset that even after Calderon’s speech before Congress, that Obama still doesn’t want to touch the assault weapons issue. There’s a great irony, also, in the photo Mother Jones chose for their article. The rifle appearing is a South Korean assault rifle made by Daewoo, which has never been lawful to import into the United States for civilian use. There is a semi-automatic variant called the DR-200, but they were made illegal for importation into the United States in 1997 because they were determined to be non-sporting under the Gun Control Act of 1968. There are very few of those in the country. Obama hasn’t reversed that determination. If you’re going to pick a firearm to illustrate the point that Obama won’t ban assault weapons, it’s probably best not to pick one that’s already banned, and still banned.
