To explain a little more about WP:V and WP:CITE take the first sentence of the second section:
In today's prisons, what would be widely perceived as torture may be common place, but not widely understood.{{Fact|date=October 2007}} [[http://www.supermaxed.com/]]. 
The sentence makes an assertion. see WP:PROVEIT "The burden of evidence lies with the editor who adds or restores material. All quotations and any material challenged or likely to be challenged should be attributed to a reliable, published source using an inline citation. The source should be cited clearly and precisely to enable readers to find the text that supports the article content in question. (my emphasise)"   [[http://www.supermaxed.com/]]  which turns into "[]" is not a clear and precise. See WP:CITE for more details on this, but as reference tags are being used in this article you should add your citations as reference tags. see [footnote 6 for how to add PDF with paragraph noted so that someone can follow you citations.
