Three students were killed and several others were wounded Monday at a Wisconsin school, police said, in the latest mass shooting to strike America’s educational institutions.

The shooting occurred at Abundant Life Christian School in the state capital of Madison. The shooter, a student at the school, was among the deceased, police reported. As of the time of writing, the shooter and victims have yet to be identified by official sources.

The school confirmed the shooting on its social media pages, asking for prayers, and stating they would follow up with more information as it becomes available.

School shootings have been at the heart of the US gun rights debate for decades. According to the K-12 School Shooting Database, school shootings have occurred in nearly every state of the country, and the number of school shootings, as well as resulting deaths and injuries, have increased dramatically over the past six years.

The Second Amendment of the US Constitution states:

A well regulated Militia, being necessary to the security of a free State, the right of the people to keep and bear Arms, shall not be infringed.

Historically, pro-gun lobbyists have effectively fought to limit federal gun regulations. Gun control laws thus vary broadly by state. Strict gun control states like California require extensive background checks for gun purchases, ban assault weapons, and strictly limit who is eligible to acquire a weapon. On the other end of the spectrum are states like Arkansas, which does not require background checks, ban assault weapons, and imposes only limited restrictions on who is eligible to acquire a gun.

Firearms rights advocates see gun ownership as an essential constitutional right, aimed at ensuring fundamental freedoms granted to all US citizens. Gun control advocates argue that mass shootings and gun violence more generally show that the Second Amendment must be interpreted with a lens to the evolution of weapons technology since the Second Amendment’s ratification nearly 250 years ago.

Some take it further and argue that the Second Amendment should be repealed. In a 2018 op-ed, former US Supreme Court Justice John Paul Stevens argued:

Concern that a national standing army might pose a threat to the security of the separate states led to the adoption of that amendment, which provides that “a well regulated militia, being necessary to the security of a free state, the right of the people to keep and bear arms, shall not be infringed.” Today that concern is a relic of the 18th century.
