Do Armed Civilians Stop Active Shooters More Effectively Than Uniformed Police?

 From John Lott at the Crime Prevention Research Center and Carlisle Moody at the College of William & Mary.

 Abstract: The FBI tracks active shooting cases-where individuals attempt to kill people in public places, excluding those tied to robberies or gang violence. This study is the first to systematically compare how uniformed police and civilians with concealed handgun permits perform in stopping these attacks. We find that civilians with permits reduce the number of victims killed, the number wounded, and the total number of casualties more than responding police officers do. They also stop the attacks more frequently and face a lower risk of being killed or injured than police. We also provide evidence that these numbers significantly underestimate the advantages of civilians over officers in stopping these attacks. We find that officers who intervened during the attacks were more likely to be killed or injured than those who apprehended the attackers later. We explore the implications of two possible identification problems. There is some evidence that Constitutional Carry laws reduce deaths and injuries from active shooting attacks.

Tylenol and Autism

 From Science Daily.

 My cursory look at some of the research suggests the same conclusion. The best study I ran across was on siblings that received Tylenol vs those that did not. That study showed no relationship.

 My maximum likelihood estimate is that RFK, Jr. blew it.
