New copyedit
Arre, I did a revision checking for sources related to each paragraph. I also tried to get the style more academic:

I added: 
 The article is structured as per Wikipidia manual of style. Created section titles. There's now an intro, a history and conditions sections. 
 Gave context to the article by linking the prison to the political life. 
 In the history section gave a better explanation of the existance of the prison by linking it to the failed coup d'état. Also added info about Mon ami le Roi book. Without a history section, the article reader would find no context to follow.
 I added  to the Saharawi inmates. 
 Added Years of lead as a see also as both subjects are related.

I removed:
 capacity for only 56 inmates. Not true. The reference given   talks about getting 56 detainees for the first time.
 summary executions occurred. In the reference we had , there is no such claim. The article puts it as a possibility. 
 The Al-Ahram weekly reference is about the book of Tahar Ben Jelloun and I put if on further readings and kept the link.
 Scorpions and snakes. I removed snakes as Al Jazeera link only reports scorpions.
 feracious is an adjective and by nature we avoid using adjectives in wikipedia in order to avoid pov issues. Cold winter is enough. 
 Surviving inmates have described the experience as "being buried alive" is not well sourced. They may describe it in all possible words but weather someone said explicitly and exactly being buried alive or not, nobody is sure. I also removed a "death camp" rather than a prison for the same reason while I believe that someone would have said it. But again, no sure. In case of statements declared by people, we have to be very carefull. 
 Approximately half of those imprisoned in Tazmamart eventually succumbed to diseases, torture or simply the winter cold, is removed because it is tackled in the same section. Duplidation.

Please check and compare the two versions if the articl's lost any encyclopedic content. Cheers     Wiki me up
ok.
