Greg Gutfeld gives a shoutout on The Five to my research

The text of Gutfeld's monologue is available here. Greg's discussion about our work is at 4:35 into the video.

At about 3:00 into the video, Juan William claims that “half of killings are done by families,” it is completely wrong. In the latest year the data is available, 2013, if you add up murders involving Husband, Wife, Mother, Father, Son, Daughter, Brother, or Sister, you get a total of 1,419. That same year there were 12,253 murders. So rather than 50%, we are talking about 11.5%. If you include "other relatives," including up to cousins twice removed, you can get the percent up to 13.6%.

Juan’s claim has been something that gun control advocates have pushed to make people afraid of those that they know having guns. What people should really be worried about is relatives who have violent criminal records. 90% of adult murderers have an adult violent criminal record.
