"social media: establishing criteria for law enforcement use" counterargument

I know every thing I said from my last post is true BUT I have something that goes against what I have said and need to speak my mind. Just because police reinforcements have a job and uses their social media for work doesn't mean that they cant have their own personal one with a different name. They desire their own private account (if desired too) of their own. That is wear they can be free and to be able to express their mind to have freedom of speech and say what ever they want (but of course not job related to be safe). During work and their personal time they need a different account where they can slack, where they can be them selves. But while on duty they must perform the task until they are done for the day. It is not fair if they take that part from them that makes them human. They have a need too, they have feelings as well they are not robots.
