There were almost 7 times the number of guns sold in Illinois than in Indiana. What about that story line of everyone going from Illinois to Indiana to buy their guns?
As my grandpa used to say, "One should never let the truth get in the way of a good story".
You can't push an anti 2A agenda or that strict gun laws work using real data, Chicago is a prime example of this, so, they have to deflect the blame on something/someplace else to stay on agenda, that is how it has been for a lot of years and for a lot of topics and for a very long time.
This is why people should do their own research.
DON'T trust my research, don't trust the media, do your own research.
Quick Stats I have found from 2016 CDC and US Department of Justice Data:
~ 35k annual gun deaths in 2016
65% Suicide
15% law enforcement in the line of duty
17% criminal activity (gangs, drugs, initiations, etc)
3% accidental discharge
So 35k is actually more like ~6k actual "gun violence" (~17% of 35K)
(note 40,000+ died from a drug overdose that year, and 36k died from car accidents)
6k (17% of 6k):
701 Los Angeles (11.7%)
480 in Chicago (8%)
344 in Batimore (6%)
333 in Detroit (6%)
119 in Washington DC (2%)
About 1/3 = 33% of all gun violence happens in 5 major cities (not states) all of these cities are in states with very strict gun laws
This basically leaves 4000 for the entire rest of the nation, ~80 deaths per state on average.
NOTE: That is an average because some States have much higher rates than others. For example, California, a strict gun law state, had 1,169 deaths and Alabama had 1.
Back to the OP and to keep this on a 2A note
You can't legally purchase a gun in Indiana if you are from Illinois unless it goes through an FFL, from what I can find, and, apparently, based on the OPs numbers, you can legally purchase a gun in Illinois if you are not a criminal and can pass a background check since the numbers of sales are from "legal sources" (Illinois resident over 21, Valid FOID Card, Valid state ID or Drivers license, and 3 day waiting period)
More fun facts: This is actually a pretty good report if you want to read it -
https://www.bjs.gov/content/pub/pdf/suficspi16.pdf
Only 1.3% (based on surveys of prison inmates by the DOJ ) of prisoners obtained a gun from a retail source, 0.8% from a gun show, and over 90% got it from a illegal source (off the streets, straw purchase, etc).
So, maybe legal gun sales are so high in Illinois (again note 98.7% of these are legal sales by people who can legally buy a firearm, not the criminals committing homicides) is because they are using their 2A right to keep and bear arms to defend themselves from those that don't follow the rules?
I tried to stay on topic and within the THR rules here,
