Super sad, and I'm assuming that moving from SF to Miami was in part due to crime issue.
Many cities with high homicide rates have them specifically because of gang activities and they don’t have any relevance to regular citizens.
Additionally, gun friendly states with “stand your ground” laws will have higher homicide rates just from self defense in robberies.
Tldr; homicide rate is meaningless to how safe you are as a bystander.
There was a notable SF->Miami exodus during COVID, we don't need to attribute reasoning we don't know here.
