While traveling back to the station in a 12 passenger van I heard XXXX refer to another individual as a ******. I wasn’t sure if I heard correctly as there were many conversations in the van that was compiled of at least 8 officers and he was sitting in the very rear and me in the very front. Even with the multiple conversations and ambient noise I heard Officer XXXX call an indivdual a ****** again. Now that I had confirmed it, I told XXXX not to use that word again. I explained that it was a well-known offensive word that should not be used by anyone. He replied, “I’ll say it when I want”. Officer XXXX, a friend of his, also stated that he would say ****** when he wanted. At that point I jumped over my front passenger seat and two other officers where I placed my hands around XXXXs’ neck and squeezed. I stated to XXXX, “Don’t fukking say that”. At that point there was pushing and shoving and we were separated by several other officers. What I should have done, was put a Winchester Ranger SXT 9mm 147 grain bullet in his skull and Officer XXXX’s skull. The Situation would have been resolved effective, immediately. The sad thing about this incident was that when Detective XXXX from internal affairs investigated this incident only (1) officer (unknown) in the van other than myself had statements constistent with what actually happened. The other six officers all stated they heard nothing and saw nothing. Shame on every one of you.
