Hello Gio1, admin who PKed you here.
Couple of things to go over for the future, if you have a clip please provide this in the future to enable further context and more clarity in future appeals.
When getting the full scope of the situation in the logs, I have to highlight this, even prior to getting hit with the baton you talk about shooting them down:
When you are hit by a baton it is while you are pointing a gun at three officers, your shooting at the officer who tries to baton you is what then caused the other officers to shoot at you.
(which can be seen in the following clip of your PK. https://medal.tv/games/garrys-mod/clips/mc0VOoDjKZfQuFIi3?invite=cr-MSwzcDQsMTg3NDA2MzY0&v=9 )
In my opinion it was a just escalation from the side of the police which resulted in your PK as you did not put your life first in the situation and were looking to evade a potential arrest by taking the officers out.
