Black Lives Matter (BLM) protests “correlate with a 10 percent increase in murders in the areas that” experienced protests, according to a study reported by the left-leaning website Vox.
The Vox report detailed a non-peer-reviewed study by University of Massachusetts Amherst Ph.D. student Travis Campbell which found that BLM protests tended to correlate with a reduction in police killings and an increase in the murder rate in cities where protests occurred.
Vox reports:
There’s long been a fierce debate about the effect of Black Lives Matter protests on the lethal use of force by police. A new study, one of the first to make a rigorous academic attempt to answer that question, found that the protests have had a notable impact on police killings. For every 4,000 people who participated in a Black Lives Matter protest between 2014 and 2019, police killed one less person. [Emphasis added]

From 2014 to 2019, Campbell tracked more than 1,600 BLM protests across the country, largely in bigger cities, with nearly 350,000 protesters. His main finding is a 15 to 20 percent reduction in lethal use of force by police officers — roughly 300 fewer police homicides — in census places that saw BLM protests. [Emphasis added]
