It doesn't lie in the province of either warders or wardens to deny a prisoner food. Should one threaten to do so he would not only anger the prisoners, he would justly earn their derision.
Is it alright for prison guards and whatnot to threaten to not feed prisoners because they're being too loud even if it's an empty threat?
Sometimes you are left with no choice but to threaten something drastic to get everyone to listen to you. Some places are run that way - using threats and intimidation to get their point across.
Of course, I don't plan on breaking the law to get me sent to the big house, because I like eating popcorn for supper sometimes. In jail, you don't get a choice.
They have to feed them here in usa federal law
No .. It is not alright. Empty threat or not .. A guard Has no say one way or the other.
