Local Boston TV gave the story 30 seconds this morning.
This tells me that the media wants this to go away. Nothing for them to gain here.
You make a good point. I remember how much publicity the Muslim gathering at the very same location rendered, not because it was a Muslim gathering but because there was ‘so much concern’ about death threats and bombing threats etc. toward participants in the event. The media showed video nationally of all the protestors and told repeatedly about the threats. This event had Muslim protestors, don’t know about threats, and an actual attack by Muslims. But the previous gathering had the Imams worried sick about someone attacking them. Publicity and brainwashing. Accuse the opponent of doing what your team would/could/might do? Probably trying to gain sympathetic publicity.
