Take this article for example:
http://qz.com/726245/more-black-people-w...-jim-crow/

"More black people were killed by US police in 2015 than were lynched in the worst year of Jim Crow."

True. But what the article doesn't talk about is population levels.
See here:

US population in 2015: 320.22 million
US population in 1965: 194.30 million
