Feb. 24, 1984: Tyrone Mitchell, 28, used an AR-15, a Stoeger 12-gauge shotgun and a Winchester 12-gauge shotgun to kill two and wound 12 at 49th Street Elementary School in Los Angeles before killing himself.
Not a mass killing. Only two were killed. Despite his use of an AR-15 to fire 39 shots in that 10 minutes (any gun can do that!), only two were killed. Not a good example of your argument.
Oct. 7, 2007: Tyler Peterson, 20, used an AR-15 to kill six and injure one at an apartment in Crandon, Wis., before killing himself.
He was also a police officer. Oops.
June 20, 2012: James Eagan Holmes, 24, used an AR-15-style .223-caliber Smith and Wesson rifle with a 100-round magazine, a 12-gauge Remington shotgun and two .40-caliber Glock semi-automatic pistols to kill 12 and injure 58 at a movie theater in Aurora, Colo.
This shooter used a Walther P22 and a Glock 19, both pistols. One a .22, the other a 9mm. No AR-15 was used. No shotgun was used. Only one Glock was used. No rifle of any kind was used.
Dec. 14, 2012: Adam Lanza, 20, used an AR-15-style rifle, a .223-caliber Bushmaster, to kill 27 people — his mother, 20 students and six teachers — in Newtown, Conn., before killing himself.
A Bushmaster is not an AR-15. It has elements of the AR-15 action in its components. Why not? It's a reliable action. It's been around long before the AR-15. You forgot the mention the two pistols he used.
June 7, 2013: John Zawahri, 23, used an AR-15-style .223-caliber rifle and a .44-caliber Remington revolver to kill five and injure three at a home in Santa Monica, Calif., before he was killed.
He used a homemade gun and a revolver. A homemade gun is not an AR-15.
March 19, 2015: Justin Fowler, 24, used an AR-15 to kill one and injure two on a street in Little Water, N.M., before he was killed.
Not a mass shooting. Another bad example of your argument.
May 31, 2015: Jeffrey Scott Pitts, 36, used an AR-15 and .45-caliber handgun to kill two and injure two at a store in Conyers, Ga., before he was killed.
Not a mass shooting. Another poor example of your argument.
Oct. 31, 2015: Noah Jacob Harpham, 33, used an AR-15, a .357-caliber revolver and a 9mm semi-automatic pistol to kill three on a street in Colorado Springs, Colo., before he was killed.
Not a mass shooting.
Dec. 2, 2015: Syed Rizwyan Farook and Tashfeen Malik, 28 and 27, used two AR-15-style, .223-caliber Remington rifles and two 9 mm handguns to kill 14 and injure 21 at his workplace in San Bernardino, Calif., before they were killed.
These were Islamic terrorists. They used modified AR-15's as well as pipe bombs. Hey...those are already illegal! Gun control laws sure didn't stop them!
June 12, 2016: Omar Mateen, 29, used an AR-15 style rifle (a Sig Sauer MCX), and a 9mm Glock semi-automatic pistol to kill 49 people and injure 50 at an Orlando nightclub before he was killed.
A Sig Sauer MCX is not an AR-15 or even patterned like an AR-15. It is a totally different gun. It doesn't even use a .223 cartridge. It uses a 7.62mm cartridge.
Oct. 1, 2017: Stephen Paddock, 64, used a stockpile of guns including an AR-15 to kill 58 people and injure hundreds at a music festival in Las Vegas before he killed himself.
Already discussed earlier. This is one example that actually supports your argument.
Nov. 5, 2017: Devin Kelley, 26, used an AR-15 style Ruger rifle to kill 26 people at a church in Sutherland Springs, Texas, before he was killed.
The Ruger is not an AR-15. It is patterned after an AR-15. It's a stretch, but I'll give you this one as number two.
Feb. 14, 2018: Police say Nikolas Cruz, 19, used an AR-15-style rifle to kill at least 17 people at Marjory Stoneman Douglas High School in Parkland, Fla.
Number three. An AR-15.
So a lot of your examples are not really examples at all. Get yer facts straight, dude.
One other thing you forgot to mention, the number of these shooters that were being treated with mind altering drugs by various psychoquacks. Drugs known to cause homicidal and suicidal tendencies.
So who killed these people? The shooter or the psychoquacks? In my opinion, BOTH.
