You stated earlier that LE is not a "group", and no group is entitled to such.
I would argue that it is an entire profession. A profession that I might add, that has frequent contact with individuals with nefarious intentions, who also have access to firearms and intent to use the same upon LE. Not to mention a profession with a job description that firearms possession and use are requisite.
The bump on your rump, is apparently the one you took for the team....if you are able to discern my meaning.
Again... cops are not a "group" such as Latinos, left handed people, midgets, and red-heads are. Yes, you can refer to a "group of doctors, hotel clerks, dishwashers and cops". But in the context of the orginal post with the question, a group implied a collection of folk who shared an inherent quality that made them similar.
The "job description" is the responsibility of the community that hires the cop. Again, they can write that job description anyway they choose as long as they don't break certain discrimination and EEOC laws. If THEY choose not to make the firearms "requisite" they have full right to do so. For example, there are many state universities in the country where the university police do not carry firearms.

Why don't you try getting a job as a campus law enforcement at one of these colleges and then demand your "right" to carry a gun in spite of the campus regulations.
This is not rocket science.
