Holiday weekend marred by multi-victim shootings in 7 states.

At least 12 people died and dozens were wounded in shootings across the US over the Father's Day weekend, with incidents reported in at least seven states. Shootings in California included a vehicular shootout in San Francisco that injured six people, and a shooting at a house party in Carson that left eight people injured. Criminologist Richard Rosenfeld noted that homicides are down from last year, but mass shootings continue to rise. A recent survey found that a majority of Americans have experienced gun violence, reinforcing the need to treat gun violence as a public health issue.
