I read a article about OVERPENETRATION that stated the NYD used 115gr 9mm Ball during that time period, and were the last ones to switch to JHP in 1999.
Pistol used was S&W 5900 DAO series and Sigs P226.
Author Mas Ayoob also listed some statistics of bystanders shot NYPD & LAPD
Don't know if its true or not .
I can see it since LE used 38spl Lead RN at one time.
I wonder how many bystanders were shot with the LRN bullet
I`m sure it can penetrate pretty far.
