while I don't really agree with op, you're stretching things here quite a bit.

a) it's a county jail, not state or federal prison. the people there wouldn't be hardened criminals there for extended stays. they'd mostly be, afaik, petty criminals and people waiting for trial dates. I suspect the spork stabbings aren't attempts at murder, particularly against prison guards (esp. considering the article says "stab someone" vs "hurl food at a prison guard").

b) the article, the part you quoted in fact, specifically calls out food-related problems, not "additional offenses". making prison wine and throwing food could probably be laboured into offenses if someone with power was vindictive enough, but those are really basic administrative issues and this nutraloaf is an administrative response.
