on average, guns did not protect those who possessed them from being shot in an assault. The study estimated that people with a gun were 4.5 times more likely to be shot in an assault than those not possessing a gun.So 40 people had guns on them. Nowhere in the article does it say they 'legally' had it on them. Most crimes occur by criminals against prior criminals. What's the percentage of Philly residents who have CCW permits? Are permit holders that much more likely to be involved in a crime?
they randomly selected 677 cases of Philadelphia residents who were shot in an assault from 2003 to 2006. Six percent of these cases were in possession of a gun (such as in a holster, pocket, waistband, or vehicle) when they were shot.
As reader Carl in Chicago noted, the PA school of Medicine has received hundreds of thousands of dollars in Joyce Foundation grants to endorse gun control.
I suspect the fisking of the report when the full version is released will be fairly simple.
Update: Here's the full article. SIH says that the methodology is completely rigged to achieve the standard Joyce line. From what I'm reading, they did include illegal possession by adults involved in criminal activities just like Kellerman did.
