If you have a criticism to make you should be able to make it using normal language. Swearing is just adding insult to the mix and building resentment. Not the best situation for a group trying to work together. Every boss that ever swore at me instantly lost all chance of co-operation and respect. Even if I was in the wrong. Wouldn't you feel the same?
You'll also lose sympathy with some members of the jury if you get to court.
I never got into the habit; one pleasant result when I was a cop; any complaints obviously included a definite lie. Criminals can't imagine anyone not swearing so usually report your language as including it.
Unlike the laughable idea that 'swearing at a mugger/ intruder will show you are serious'.
