It is a fact that even being the most popular long gun in America it only accounts for 3% of all homicides. Even when I tell my conservative friends this stat they are surprised. But.... they are trending in the most popular for school or 'mass shootings' they are easier for people who cant shoot to .... well.... shoot. reliable and powerful.
About a hundred people are killed a year in 'mass shootings' 136 in 2021 for instance. 100-136 is hardly a large number in a nation of 350 million people. Where we have over 3 million deaths a year.
Sooo.... say I was a mass murderer and I could not get my hands on one of the TWENTY MILLION Ar's in America and several million other semi auto rifles.... I would go all Josey whales on em. 4 revolvers with speed loaders. .357 mag... 90% chance of fatal wound... 8 shot each (yes they make 8 shot revolvers) That would be 32 people shot it would of course take me almost a minute to reload all those guns when empty but then... back in business.
Of course it only accounts for 3%. The AR-15 type isn't really for killing. It's just something for drooling mouth breather overweight tacti-cool wanna be militia cowards to hang a bunch of useless optics and accessories from.
