This is a very contentious issue, and both sides have numerous studies to cherry-pick to support their side. In a search of academic articles (as opposed to blog posts), I have come across a couple that I feel are relevant, well sourced and conducted, and impartial.
Harvard University published a report in October of 2010. Some key points:
Much of ...
The numbers are cherry-picked.
When you dig into sites that present this argument, they all appear to be strong advocates against regulating firearms, which makes me suspicious. Is this statistic true? If it is accurate, on the surface, are there deeper conclusions we can draw from it?
Correlation is not causality, and they ignore other factors on crime. ...
As discussed in this answer and this answer when you use a term like "mass shooting", your results become particularly sensitive to your definition. Additionally, results will be sensitive to search strategy, since cases are assembled from searches for news reports. Because the results are sensitive to definition and search strategy, they are susceptible to ...
The answer seems to be no on all accounts.
In general, Snopes says:
Although the meme is of recent origin, Internet mentions of this alleged historical fact date to at least 2003. Significantly, however, we were unable to trace it back any further than that, nor could we find any credible support for the general claim that it was common to use ammunition ...
This is false no matter what way you try to frame it.
Using the 2019 crime stats:
US: 15020 
Chicago: 491 
Detroit: 273 
New Orleans: 120 
St. Louis: 194 
Washington DC: 166 
These cities have a combined census population of 4.67m (out of 308.75m for the USA), which is ~1.5% of the total US population 
Removing those 5 cities ...
It depends on your definition of terrorism and your interpretation of the quote: is it about American lives anywhere in the world, or about death in America including non-Americans. For the purpose of this answer I'll assume the second interpretation.
If terrorism only includes Islamic terrorism, it would be true, although quite close. See for example the ...
According to the FBI homicide data, there were 15,070 reported murders in the United States in 2016, 11,004 of which were victims of murder by guns: 7,105 handgun victims, 374 rifle victims, 262 shotgun victims, and 3,263 victims of murder by a different type of gun, or by an unspecified gun. In comparison, there were 472 reported victims of murder by blunt ...
I've written about the issues with defining a "mass shooting" in another answer previously. I'm going to copy and paste the pertinent parts here.
The main problem with statistics like these is that there is no one definition of "mass shooting" and thus, by adjusting your parameters, can make the number be whatever you want to fit a ...
It depends on the definition.
This article in Mother Jones says:
Studies indicate that the rate at which public mass shootings occur has tripled since 2011. Between 1982 and 2011, a mass shooting occurred roughly once every 200 days. However, between 2011 and 2014 that rate has accelerated greatly with at least one mass shooting occurring every 64 days ...
In a comment, @MikhailGerasimov gave a link to the list of incidents.
By browsing this it is clear that the claims include acts of terrorism and war. (But being curiously selective about it, I found no reference to attacks by US or allied forces in Afganistan, only Taliban and its allies)
There is no war going on in the US. There are very few terrorist ...
If you actually read the first OP article, it quotes David Keene as saying (in 2013):
You know, last year and the year before according to  FBI statistics, more people in this country were beaten to death than were killed by long arms -- so-called assault weapons -- the government sought to ban...More people were killed with hammers than were killed ...
Snopes explains it as cherry picking:
The first thing to note about the rankings is that Lott has compared
the mass shooting death rate in the United States with that of other
countries where there was a mass shooting between 2009 and 2015. This
might seem obvious, but it’s important to point out that very many
countries did not see a single mass shooting ...
In the television show Penn and Teller Tell A Lie, a competitor to Mythbusters, they conduct an experiment to try this.
Here is a YouTube video of the result.
In the single instance they show with a slow motion camera, the bullet is indeed at split in half - or at least, fragmented into pieces - by a normal butter-knife. This is not a large sample, and ...
This is not possible based on the information given. The link you provided has the US at 6th with 16,214 murders and 189th place is a 3 way tie with 9 murders each.
Using this data that would require that those 6 cities accounted for all but 9 murders in the country.
If you look at the overall stats for the country you will find this is impossible.
Update (7/6/21): Within 12 hours of my writing this answer, CNN has edited their article. The original claim can be seen here. CNN now acknowledges "a 26% drop [presumably in deaths] from last year's holiday weekend." The tone of their article has slightly changed and CNN has stopped portraying the deaths over the 4th of July weekend as part of &...
In the Atlantic article The States With The Most Gun Laws See The Fewest Gun-Related Deaths, originally published in The National Journal, a chart is presented that shows gun related deaths compared to key gun laws (not republished here due to copyright).
There does appear to be a correlation between gun restrictions and gun deaths, with the top 6 states ...
Did the 2nd Amendment really limit the purchase of cannons from the day it was passed?
No. The 2nd Amendment protects "the right of the people to keep and bear arms" and does not single out cannons or any other weapon individually.
The Second Amendment states simply (.gov site)
A well regulated Militia, being necessary to the security of a free ...
TL;DR? The USA has so many mass shootings that the average deaths-per-shooting is lower than other places.
Let's break down what he's calculating: The rates of murder from mass public shootings per million people.
This means that, when there is a mass shooting(1) in public(2), that if we account for population(3), more people are murdered(4) .
By using ...
The info-graphic says there's a problem in "Democrat Inner Cities".
Apparently, inner cities in general are Democratic.
Here's a liberal source saying so:
Democrats are from cities, Republicans are from exurbs
Princeton's Robert Vanderbei put together a fantastic 3-d map in 2012, which I'd recommend that you take some time to explore, that visualizes ...
First-person shooter games with human targets did not exist before Wolfenstein 3D in 1992. There were some brave attempts (most notably Aliens and Operation Wolf) but nothing which allowed the player to freely explore the environment. (As pointed out by Tyler, there were earlier FPS games, but none which were violent.) Note that I'm making the assumption ...
No they haven't.
Searching Google for the picture brings up this fallowing blog post which address this picture particularly. It cites the 2011 Australian Crime Report (alternative link) published by the Australian Institute of Criminology.
from the post:
Below is a chart from the annual Australian crime stats report for murders — the short version: ...
There are two separate claims here.
1) The Daily Currant says Georgia has legalised handguns.
No, this is just a story from the Daily Currant which is a satirical magazine that invents stories.
2) That the image on the "17 Most Unusual Vending Machines" demonstrates that there is a vending machine that sells guns.
No, this is just an donation drive, ...
There is little evidence upon which this list is based, even after
extensive searches, and many of those records seem to be inaccurate, or
To quote Snopes:
We searched contemporary reports for each of the listed incidents in
an attempt to uncover any mentions of political affiliations,
motivations, or voting records. Many of these items can ...
First, the American firearm-deathrate according to this table is 10.1 per 100,000 people, but the yellow swatches in the Infographic are, according to the legend, areas that have less than that rate. Conversely, the entire states of Lousiana, Alabama, Mississippi, Wyoming, Montana... well, actually, 30 entire states ... should be colored in green (indicating ...
Maybe - there is preliminary evidence that supports it.
The Economist article is referring to this very recent working paper:
Luca, Michael and Malhotra, Deepak K. and Poliquin, Christopher, The Impact of Mass Shootings on Gun Policy (May 4, 2016). Harvard Business School NOM Unit Working Paper No. 16-126.
They found that:
when looking at enacted laws,...
Per Anthony J. Pinizzotto, Harry A kern and Edward F. Davis in FBI law enforcement bulletin October 2004, with the exceptions of hits to the brain or upper spinal cord, the concept of reliable and reproducible immediate incapacitation of the human target by gunshot wounds to the torso a.k.a one shot drop is a myth. However, many shooting scenes in majority ...
The meme is unclear
It is not clear whether the meme is talking about absolute numbers or per capita murder rates. I'll talk about both.
The meme does not distinguish murder vs homicide
The first thing to note is that murder is a legal term, not equivalent to homicide. Murder does not include accidents or various manslaughter that led to homicide without ...
The word "Shot", a corruption of the Late Old-Engish "Scot" or "Secot", itself a corruption of the old Norse "skot", was a word meaning a Tax or measure. This means it pre-dates not just the "Wild West" period of American history, but also the invention of the first firearms.
A cannon used to fire either a large Cannonball or a measure ("shot") of smaller ...
Yes, it is possible for one to get a shot off after being shot in the head oneself.
Here are two different examples, both involving cab drivers being shot in the head and still returning fire.
For the first example, see St. Louis Cab Driver Shot in Head, Returns Fire and Drives to Police Station for Help
This was a serious enough head injury that the cab ...
Muzzle-loading, black-powder firearms firing solid shot, including cannons, such as the ones used in the US War of Independence and Civil war have never really been subjected to any regulations.
You buy one today, with no license(or any other checks) required, from companies that sell antiques or make functional replicas for enthusiasts e.g:
For example, ...
