To bounce off my previous post that linked Roger Ebert's column after the shooting in Colorado ("The Body Count"), one of Clarence Page's recent op-ed columns discusses the options we might have to revise gun laws. If you're interested, here's "My Quest for Commonsense Gun Laws."
Below is the video of al-Qaida spokesperson/recruiter Adam Gadahn that Page mentions at the end of his article.
For a less scary set of points about gun laws and gun control, one that comes from an unlikely source, is "The 4 Most Meaningless Arguments Against Gun Control" on Cracked.
To take Cracked's lead, we might be able to boil it all down to a concise and snarky maxim that is a tweet from the comedian Rob Delaney: "Guns don't kill people. People who say 'Guns don't kill people' kill people. With guns."
