Well, it's all opinion based, so here is mine:
I would study old Law and Orders or other gritty crime dramas before they allowed much swearing on TV. With good writing, you don't even notice it, at least for me.
That being said, if you are OK with swearing, I would use it sparingly, to give it more impact!
Just my opinion. You know the nature of the game and how things fit better than us
