At the age of 70 my memory goes back a ways and I recall when hollowpoint ammunition was considered "Inhumane" and there was quite a bit of controversy over the use of Hollowpoint ammunition and many police agencies prohibited it.
Concerned citizens and the ACLU (All Criminals Love Us) felt that since police shootings involved only those who were suspected but not yet convicted of committing a crime who might later be proven innocent, that it violated their civil rights to be shot with ammunition that resulted in greater fatalities.
I lived in Los Angeles in the 60's and the 80's and had friends in both the LAPD and the sheriff's department and the LAPD only approved the use of HP ammo as recently as 1990 decades after the first hollowpoint ammo was developed.
In the link that I posted about the 41 magnum, it says,
"The .357 Magnum suffered from restricted
terminal ballistic effectiveness in the early 1960s, as
jacketed hollow point bullets were not yet commonly available, and the major
manufacturer's standard loadings consisted of simple
lead bullets."
For the early 60's, this was absolutely true.
Lee Jurras began marketing Super Vel ammo in 1964 but this ammo was not commonly available that year when the 41 magnum was developed as a police cartridge, and not all, but many departments were reluctant to issue hollowpoint ammunition for many years afterward.
