ISIS laptop with bioweapons 19-page document

     The news broke this week that an ISIS laptop had been captured and a document outlining bioweapons was found on the computer harddrive. The owner of the laptop was purportedly a Tunisian member of ISIS who had attended a university in Tunisia in physics and chemistry.  Foreign Policy was the first to break the story and it has been reported by so many news outlets and blogs that I never reached the end of my Google string query.  That said, I will add only what I think has not been said about the information that was found.
     The "19-page document" on the laptop harddrive that serves as the article's only source contains such quotes as:

"Use small grenades with the virus, and throw them in closed areas like metros, soccer stadiums, or entertainment centers. . .Best to do it next to the air-conditioning. It also can be used during suicide operations."

     The Foreign Policy authors write, "The ISIS laptop contains a 19-page document in Arabic on how to develop biological weapons and how to weaponize the bubonic plague from infected animals."

Then the authors quote from the 19-page document:

"The advantage of biological weapons is that they do not cost a lot of money, while the human casualties can be huge," . . . 

    Then some instructions on testing a plague weapon, according to the authors:

"When the microbe is injected in small mice, the symptoms of the disease should start to appear within 24 hours. . . ."

    These few phrases tell us a world of information about the stage of development and level of understanding of ISIS's members ---and this is not to be ignored.
