Can you explain?
Virginia has lax gun control laws and a Constitutional provision that denies Virginia cities to enact any stricter laws. The District of Columbia has one of the country's strictest gun law regimes. Yet crime in DC is far higher than Arlington VA, right across the Potomac.
DC saw 8,200 violent Crimes and 34,000 property crimes per 100,000 residents.
Arlington: 104 violent crimes and 1,213 property crimes per 100,000 residents
