After the Parkland massacre, more states consider 'red flag' gun bills - CNN
Even before the Parkland school shooting raised questions about warning signs exhibited by gunman Nikolas Cruz, at least 19 state legislatures were already considering "red flag" bills that would let a court temporarily prohibit someone from possessing or buying firearms if they're deemed to pose a threat to themselves or others.
Now even more states are considering such laws after the February 14 massacre at Florida's Marjory Stoneman Douglas High School, which galvanized discussion about them even at a national level and prompted House Democrats
propose grants for states that enact them.

Such laws -- variously known as extreme risk protection orders (ERPOs), gun violence restraining orders and red-flag laws -- are in effect in Connecticut (enacted in 1999), Indiana (2005), California (2014), Washington (2016), and Oregon (2017). -
