Wow! One whole year?
According to Statista, out of 126 mass shootings in the last forty years, 66 were perpetrated by white individuals. Do I really need to explain the role of sampling size in statistical analysis?
Yes, please do explain why statista only listed 126 mass shootings over the last 40 years while gunviolencearchives.org listed over 350 in 2015 alone. GVA.org listed nearly 700 mass shootings last year and 135 already this year.
Just kiddin', there is no need to explain, I already know why. There are no sample biases in the GVA data, their statistics are based solely on the raw numbers. Four or more wounded or killed, nothing else matters.
Statista's numbers comes from the left-wing rag 'Mother Jones' and their arbitrary method of what counts as a mass shooting.
From Mother Jones
Our research focused on indiscriminate rampages in public places resulting in four or more victims killed by the attacker. We exclude shootings stemming from more conventionally motivated crimes such as armed robbery or gang violence.
Well now, how convenient of them to leave out gang violence and shootings at parties and at bars/clubs and drive-bys.
Let's take a little gander at the Mother Jones data. The only mass shooting they have listed so far this year was from February 28. It was a familicide shooting at a Sacramento church that left four dead.
Let's see what they left out of the January and February data.
4 dead, 1 wounded in Inglewood, California.
6 dead in Milwaukee, Wisconsin.
5 dead, 2 wounded in Corsicana, Texas.
2 dead, 14 wounded in Charleston, Missouri.
10 wounded in Bogalusa, Louisiana.
2 killed, 9 wounded in Phoenix, Arizona.
1 killed, 13 wounded in Las Vegas, Nevada.
I chose these eight because they had four or more deaths, the number MJ uses, or at least double digit number of victims, that way the sample is small enough to examine for details. This will leave 70 mass shootings excluded for the months of January and February.
Of the eight 'big number' shootings listed, one shooter was white, one shooter was Hispanic and four shooters were black. In the other two shootings, Milwaukee and Englewood, there are no publicly available descriptions of the shooters. All of the victims in those two shootings were black and since, statistically speaking, people are murdered by members of their own race, it is probable that the other shooters were black as well. One of the shootings had at least three shooters.
That would mean 8 out of 10 mass shooters were black.
Actually, if you look at a statistically valid sample, using forty years of data rather than just one, the demographics of mass shooters look pretty close to the general population - 52.38% of the 126 mass shooters being white, while, currently, 57.8% of the U.S. population is white.
You're not the first person on the forum to be hoodwinked by a left-wing organization whose data hides the truth, you won't be the last.
