This is our current stance on players without a microphone, which is unfortunately not going to change:
As for the usage of VOIP, it has been answered multiple times. We have nerfed ourselves as a faction and continuously look what we can do to maintain that balance. Our goal is providing quality police role-play, while maintaining an effective in-character police department. VOIP is heavily moderated by experienced senior faction members and we do not condone it being overused.
We are going to be continuing to moderate it heavily and using it, alongside the Los Santos Sheriff's Department. Both factions have been moderating this for years since 2018, and we continue to do so.
I suggest you send a suggestion to Server Management regarding the usage of VOIP in LEO factions, if you really want to see it gone.
For returning players who have yet to experience our changes and had bad interactions with our faction, I can only hope that our faction’s role-play standards and changes can make up for the past!
We've re-introduced Robbery and Homicide Division. We are also looking into opening forensic positions for players, it depends on the script and how detailed it will be though. @bobster and @lynx should be able to get into more detail about this with you.
I suggest that you conduct your own research in regards to the inner workings of American law enforcement agencies. Numerous bodycam videos can show you exactly what you are describing as unrealistic behavior, that being officers calling out the situation and their location immediately upon returning fire, or during the gunfight.
Their objective during emergency situations is to call the situation out and get their colleagues to come help them, rather than 'eliminating the threat' solo like Rambo, or 'running away' from an emergency incident with the risk of getting shot in the back.
LAPD's Youtube channel may help you out with understanding how these agencies work.
