It is not just in Florida where the mass shooting at a high school is prompting lawmakers to take up gun control legislation. The same thing is happening across the country, from Washington to Vermont.

What was one of the deadliest school shootings in modern American history prompted Gov. Gina Raimondo of Rhode Island to sign an executive order on Monday to establish a policy to take guns away from people who pose a danger to themselves or others.

“If the federal government won’t act, states need to do more to prevent the gun violence that has become far too common,” Ms. Raimondo, a Democrat, said in signing the measure.

Many of these measures to address gun violence come as students around the nation, accustomed to inaction in Congress, have begun protesting. The most vocal have been the survivors of the shooting, which left 17 dead in Florida on Feb. 14.
