Local Jail Claims That Inmates Are "Residents" And Are Exempt From Wearing Face Coverings

The above is in response to a grievance filed by an inmate at our local jail asking for better protection from the coronavirus. But the Sheriff believes inmates aren't required to wear masks because the jail is their legal "residence," and that jail employees are exempt because they are a part of a "law enforcement agency." 

This raises some interesting legal (and liability?) questions.
