5. More guns = more homicides of police
This article examines homicide rates of Law Enforcement Officers (LEOs) from 1996 to 2010. Differences in rates of homicides of LEOs across states are best explained not by differences in crime, but by differences in household gun ownership. In high gun states, LEOs are 3 times more likely to be murdered than LEOs working in low-gun states.
This article was cited by President Obama in a speech to a police association. This article will hopefully bring police further into the camp of those pushing for sensible gun laws.
