Via One-Foot Tsunami, Scientific American on the evidence that gun control measures are not only supported by the data, they are popular with Americans:

As we previously reported, in 2015, assaults with a firearm were 6.8 times more common in states that had the most guns, compared to the least. More than a dozen studies have revealed that if you had a gun at home, you were twice as likely to be killed as someone who didn’t. Research from the Harvard School of Public Health tells us that states with higher gun ownership levels have higher rates of homicide. Data even tells us that where gun shops or gun dealers open for business, killings go up. These are but a few of the studies that show the exact opposite of what progun politicians are saying. The science must not be ignored.

The Science Is Clear: Gun Control Saves Lives
