It seems like the 70s were rampant with serial killers. Ted Bundy, Son of Sam, John Gacy, Charles Manson, The Hillside Strangler, etc. The 80s were full ofserial killers as well but as we’ve gotten into the 2000s and 2010’s it seems like they’re not as common. It’s less serial killing and more mass killings in a single event such as the Las Vegas shooter. Why is that?
