Junk science is just as pervasive as bad journalism and is often more politicized. If you have honesty results in a  data set that happens to go  against the woke narrative your career is in jeopardy.

The shooting that killed three people and injured another at a Greenwood, Indiana, mall on July 17 drew broad national attention because of how it ended – when 22-year-old Elisjsha Dicken, carrying a licensed handgun, fatally shot the attacker.

While Dicken was praised for his courage and skill – squeezing off his first shot 15 seconds after the attack began, from a distance of 40 yards – much of the immediate news coverage drew from FBI-approved statistics to assert that armed citizens almost never stop such attackers: “Rare in US for an active shooter to be stopped by bystander” (Associated Press); “Rampage in Indiana a rare instance of armed civilian ending mass shooting” (Washington Post); and “After Indiana mall shooting, one hero but no lasting solution to gun violence” (New York Times).

Evidence compiled by the Crime Prevention Research Center shows that the sources the media relied on undercounted the number of instances in which armed citizens have thwarted such attacks by an order of more than ten, saving untold numbers of lives. Of course, law-abiding citizens stopping these attacks are not rare. What is rare is national news coverage of those incidents. Although those many news stories about the Greenwood shooting also suggested that the defensive use of guns might endanger others, there is no evidence that these acts have harmed innocent victims.

The FBI reports that armed citizens only stopped 11 of the 252 active shooter incidents it identified for the period 2014-2021. The FBI defines active shooter incidents as those in which an individual actively kills or attempts to kill people in a populated, public area. But it does not include those it deems related to other criminal activity, such as a robbery or fighting over drug turf.

An analysis by my organization identified a total of 360 active shooter incidents during that period and found that an armed citizen stopped 124. A previous report looked at only instances when armed civilians stopped what likely would have been mass public shootings. There were another 24 cases that we didn’t include where armed civilians stopped armed attacks, but the suspect didn’t fire his gun. Those cases are excluded from our calculations, though it could be argued that a civilian also stopped what likely could have been an active shooting event.

The FBI reported that armed citizens thwarted 4.4% of active shooter incidents, while the CPRC found 34.4%.
