I suspect the data from 50 or 150 years ago would be similarly distorted. "Old person dies of old person disease" does not make the news.
Also the idea that homicide rates were much higher a century ago is colored by media and entertainment. The graph on the second page of https://pmc.ncbi.nlm.nih.gov/articles/instance/1435670/pdf/p... (PDF) shows homicide rates in the 1970s exceeding that of the prohibition era, which itself was a huge spike over pre-prohibition rates.
