I'm sorry, but this statistic:
>>Violent crime is falling, with homicides down ~21%. The largest annual drop on record.
...has been heavily polluted by improvements in trauma care, particularly hemostatic (blood clotting) bandages.
US Trauma care & FBI statistics🧵
1/
The statistical comparison in the FBI data from pre-1961 is invalid as the underlying medical systems have so changed as to utterly pollute the "murders per 100,000" data.
Violent crime data pre-1961 and post 1961 are apples to oranges comparisons.
2/
-Trauma care centers (1961),
-Standardized trauma procedures (1978),
-Adoption of military Korea/Vietnam medical emergency treatment & air transport procedures,
-Improved triage (1986)
-And (since 2011) widespread adoption and use of blood clotting bandages...
3/
...have drastically reduced death in the USA from severe injury.
Adjustments upward on murder data post 1961 are required to account for reduced mortality from the same level of wounds in order...
4/
...to have direct data comparisons to understand real US cultural levels of lethal violence.

It is just now the case that trauma medicine improvements between the 1950's and 2020's are so hugely more effective in the 2020's than pre-1961 that it would require an extensive rebase lining of the data set to account for each tranche of improved trauma care.
