One last decode that is embedded in the messages:
This one too is associated with the Forward Slash (code 187 murder death kill).
Line "F-I/D-J ASSIST" F=6 I=9 (matches 6 of 9 coding). D=4 J=10 (matches 4 of 9 and 6+4= 10).
So the left side is pointing to FBI and DOJ with the forward slash between the FBI DOJ (F-I/D-J ASSIST).
I believe Q was pointing to this important relationship as it defines the FBI & DOJ were complicit in the 187 murder death kill ("/" <=murder death kill, the Forward Slash code).
