From the Document: "In the last year, federal and state legislators have shown increased interest in passing so-called 'red flag' or 'extreme risk protection order' firearm laws. In general, such laws permit courts to issue temporary orders barring particular persons from possessing guns based on some showing of imminent danger or a risk of misuse. Following the February 2018 shooting at Marjory Stoneman Douglas High School in Parkland, FL, states have increasingly considered and enacted red flag laws. Legislation has also been introduced in the 116th Congress that would supplement or incentivize these state laws, criminalize at the federal level violations of qualifying extreme risk protection orders, or both. The Senate Judiciary Committee held a hearing on the subject of red flag laws in March 2019."
