"Outside of a dog a book is man's best friend. Inside of a dog it's too dark to read!"
Groucho Marx.
Banned books are an especially sad expression of social control. Having been raised Jewish I knew that societies had banned books and learnings in the past, it was as an adult that I came to understand that my native ancestors had also been stripped of their teachings and language.
Banning information as a form of oppression seems quite effective, doubly so for detainees.
In the mid 90s I read Behold a pale horse, I am one of those tin foil hat guys... to say that the information in William Coopers book was terrifying would be an understatement. As the decades have rolled by his book reads more like a history than a whistle blowers call to action. Among those pages you will have read that the first to die in the event of a hostile invasion of American soil will be the prisoners, lest they turn against the state which has turned against them.
Great post! Stay liberated.
