States passed some gun laws after recent mass shootings -- but partisan patterns were the norm, AP analysis finds

Shortly after last year's shooting massacre on the Las Vegas strip, Ohio Gov. John Kasich convened a working group to explore possible reforms to state gun laws.

A Republican, Kasich wanted to be sure the panel's members clearly supported the Second Amendment. Yet it also was to be bipartisan, with members from across the political spectrum.

The panel's work accelerated after the Valentine's Day slaughter at a high school in Parkland, Florida, and it eventually produced a legislative package of what Kasich labeled "sensible changes that should keep people safer." The legislation was introduced by a Republican lawmaker in the GOP-dominated Legislature.

It went nowhere.
