The worst mass shooting in modern American history that killed 59 people at a Las Vegas music concert and injured hundreds more has prompted the nation to re-examine gun control laws. Take a look back at the history of gun control in America.
Oct. 5, 2017: Prominent Republicans, including House Speaker Paul Ryan, as well as the NRA, said they are open to banning "bump stocks," which the Las Vegas shooter used to maximize the damage done by his assault rifles.
1791: Congress adopts 12 amendments to the U.S. Constitution, including the 10 that are known as the Bill of Rights. Among those rights is the Second Amendment, or the right to keep and bear arms. It reads: "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."
One of the earliest arguments over gun rights in America was whether slaves should be allowed to carry them. In its historic 1856 Dred Scott decision, the U.S. Supreme Court stated it would give slaves who are recognized as U.S. citizens the "full liberty" to keep and carry guns wherever they went.
In the 1990s, gun politics took a turn to the right in response to two deadly standoffs involving the Bureau of Alcohol, Tobacco and Firearms -- the 1993 Waco siege involving the Branch Davidian compound in Texas and the Ruby Ridge siege in northern Idaho in 1992.
In 1993, President Bill Clinton signed the Brady Handgun Violence Prevention Act into law. The act, which instituted federal background checks on firearm purchasers in the United States, was named after James Brady (left), who was shot by John Hinckley Jr. during an attempted assassination of President Ronald Reagan on March 30, 1981.
The ban on assault weapons expired in 2004 as part of the law's sunset provision. There have been multiple attempts to renew the ban, but no bill has reached the floor for a vote.
In the past, polls have found a majority of Americans do not support stricter gun laws. But that support has reached a five-year high in the aftermath of the elementary school shooting in Connecticut that left 27 dead.
In October 2017, gunman Stephen Paddock killed 59 people and injured hundreds more at a country music concert in Las Vegas, Nevada. The death toll qualified the massacre as the worst mass shooting event in modern U.S. history.
