I mean, when an FBI or LSPD types /hidebadge to get a message with "You concealed your badge" and simply make their names white from blue and when they type again to get a message with "You took out your badge" and make their names blue from white.
For LSPD I have "IsACop"
And for FBI I have "IsFBI"
PS: A command that makes only feds and officers name white from their duty color, blue and vice versa.
