All the laws below and none of them prevented the tragedy. A good guy with a gun stopped it from being worse. Go ahead and keep thinking another law would prevent it when all the other laws failed. Maybe students should print out gun and homicide laws. They can hold them up to explain to the shooter why it’s illegal. That’ll stop it, since I’m sure the shooter is simply unaware that what they are doing is illegal.

“The 2013 law:
Bans the sale or transfer of 45 firearms defined as assault weapons, including AR-15 models similar to that used in Parkland and other recent mass shootings. Individuals who owned such guns before Oct. 1, 2013, may continue to possess them.
Bans the manufacturing, sale or transfer of detachable magazines with a capacity of more than 10 rounds of ammunition.
Prohibits possession of so-called “cop-killer” bullets during the commission of a crime of violence.
Creates a licensing system for the purchase of handguns under which individuals are required to undergo a criminal background check and to be fingerprinted. Applicants must certify under penalty of perjury that they are not prohibited by state of federal law from owning a handgun. Most applicants must complete a certified firearms training course.
Requires gun dealers to keep records of all firearms transactions and the state police to inspect dealers’ inventory and records every two years.
Restricts possession of firearms by individuals with a history of mental illness.
Bans certain categories of people from owning rifles or shotguns, including those with criminal convictions, mental illnesses or drug addictions.
Previous laws:
Prohibit sale and possession of 15 specific handguns classified as “assault pistols.”
Ban people convicted of crimes involving violence or drugs from possessing regulated firearms, including the assault weapons whose sale was banned in 2013.
Require firearms dealers to be licensed by the state.
Require individuals carrying handguns, concealed or not, to obtain a permit from Maryland State Police, for which they must have a “good and substantial reason” to do so. In practice, few are issued such permits.
Require handguns manufactured after 2002 and sold in Maryland to have internal trigger locks.”
