Where are you getting this statistic? A quick google search doesn’t show any such surge in the murder rate in the United States. 60% is a very large increase. I would expect this stat to have huge ripple effects if it were true.
Here is the murder rate graph - note that the most recent year is flagged as not fully reported yet.

Up 60% isn't far off, depending on when "pre-BLM days" starts, but it takes a big leap to connect it to BLM.
Also, if you look at the rate since the early 90's we are doing quite a bit better, so you get to pick your favorite trend line.
My 60% figure was grabbing the homicide count in 2014 from the FBI UCR (14,249 per https://ucr.fbi.gov/crime-in-the-u.s/2014/crime-in-the-u.s.-....) and comparing it with the stats from 2021 (22,900).
