Justice For Arfee FB: WINNING!

From Justice for Arfee Facebook page: ” As Craigs friend, I am so very happy for this news today! I started this page to try to help my friend and FINALLY, we have some justice happening! This is an enormous step in the right direction! Please join the Rally on Sunday if you can! News crews will be there, and they all want to hear from Craigs friends! Thank you — Kiela ”

And: ” I have given Craig the news, as he is out of town. He is quite choked up at this time! I am also very elated, and crying happy tears!!!”

Question: What role has the social media played in the Arfee shooting situation?
