The biggest problems facing prisons and jails are the loss of uniformed security officers, and the failures of the supply chain and outsourcers.  The latter is, in my opinion, the biggest threat.  Many states and localities have outsourced their food service operations.

Many would confide that outsourced food service is terrible on a good day; imagine what will happenwhen those firms cannot deliver food in Week Three of a pandemic.  And food will be scarce in a 1918-type, even an 1889-type pandemic.  the JIT supply chain will crumble.  And with it will be any realistic chance of feeding inmates.  

This should drive states toward being more self-sufficient in the food area.  State correctional agencies should be moving decisively toward raising their own cattle, fowl and vegetables again.

Inmate industries should also be reaching out to manufacture enough masks to cover (no pun intended) all security staff; data center staff; and key administrative and leadership posts.  Inmates could also make masks for other state agencies who cannot afford to buy them.

How to make sure inmates do not make inferior masks?  tel lthem they will also be going to their families at visitation; they just won't know which masks are to be used.
