- Recent historical research documents 157 homicides in Kansas between 1854 and 1861. Of those, only fifty-six can be directly attributed to political differences regarding slavery – roughly eight deaths per year. By comparison during the 1850s, Los Angeles County, California experienced homicide rates ranging from 110 to 414 deaths per 100,000 people.
- Much of the hysteria engendered by the turbulence in Bleeding Kansas was a product of sensationalized reports published by Northern and Southern newspapers intended to foment the passions of pro and anti-slavery partisans.
- The politicized accounts of violence that occurred in Bleeding Kansas intensified the sectional polarization that eventually spawned the Civil War.
