[ec]:::::I guess that depends on how  you describe "journalist." He has done a number of interviews for magazines on other issues (such as this one ) as well as commentary and opinion.  He seems to be multi-faceted.  In the original JP article he is acting as a journalist when he provides a quote from an eyewitness whom he interviewed.  He is perhaps also expressing his personal opinion, based on his participation, knowledge, and personal experience.  He is published in a RS.  With respect to the fact that he is a blogger, no, he writes for numerous other academic journals and respected publications.  I will find them for you.
