Was it as prevalent then as it is today? Can someone point me to the statistics?
shareIt's not prevalent today at all. White people are killed by white people 85% of time. In other words, it's regional. Go read the FBI stats.
share2015 numbers, FBI UCR are the most recent data we have:

~8.5% of Black murders are at the hands of Whites
~15.8% of White murders are at the hands of Blacks
Did you have a particular year in the 1960's in mind to ask about?
