Something different is happening after the Parkland, Florida, shooting.
A renewed national conversation about gun control has prompted some states to take immediate action in the wake of the Valentine's Day massacre at Marjory Stoneman Douglas High School.
While some steps have been taken on the federal level, the laws that have changed so far are on the state level. The most sweeping legislative changes after the Parkland shooting have come in Florida, but there have been other measures passed elsewhere.
There are a number of states where new measures are being discussed or debated, but few have signed any such measures into law.
Here is an overview of the changes to laws relating to guns and school shootings that have actually been passed since the Feb. 14 shooting:
The first gun-related bill that was passed in the wake of the Parkland shooting had been introduced before it happened.
“I'm proud to sign this bill, making Oregon the first state to take action to prevent senseless gun violence since the tragedy in Parkland, Florida," Gov. Kate Brown said in a statement released that day.
The bill is said to close the so-called boyfriend loophole, as existing laws generally pertain to spouses and live-in partners but do not explicitly include romantic partners who do not fall into those categories.
The policy does not give law enforcement new authority to confiscate guns, but it directs them to use "all available legal steps" to remove firearms from people who have shown warning signs, including recently making threats of violence online or in person, according to the statement.
A bill was passed including a number of gun law reforms, including a mandatory three-day waiting period to buy a gun and raising the age to buy a rifle to 21 years old.
The law also included a measure to arm some teachers and other school personnel who undergo special training sanctioned by the state. There was a provision that allows school districts that don't want to participate to opt out of the program.
Gov. Jay Inslee signed a bill on March 6 banning the sale and use of bump stocks, which were used in the Las Vegas shooting in October.
In his tweet about the passing of the law, Inslee named Parkland as one of the "many other locations whose names have become synonymous with tragedy."
Federal steps in motion
The so-called "Fix NICS" measure, which includes the acronym for the National Instant Criminal Background Check system, is a bipartisan proposal that has been approved in the House but stalled in the Senate.
Similarly, the STOP School Violence Act passed in the House on the same day as the National School Walkout but has not been addressed in the Senate. The bill authorizes $50 million per year for grants administered by the Department of Justice to fund training and other initiatives intended to enhance school safety, and $25 million annually for physical improvements such as metal detectors, stronger locks, and emergency notification and response technologies for schools to notify law enforcement of emergencies.
