Mohamed Osman Mohamud, a Oregon State University student, had planned to set off a car bomb at a 2010 Christmas Tree lighting ceremony in Portland, Oregon before he was caught (in a setup). His friends had no idea. Now, with hindsight, they're writing letters to him.
Bassam Tariq of the "30 Mosques" project, gave all of Mohamed Osman Mohamud's, known as 'MoMo', friends a Livescribe Smartpen and asked them what they would say to him now if they could. It's an interesting question: how do you treat a friend now knowing that he was a terrorist that wanted to kill innocent civilians? The responses were varied: some reminisced about the simpler past, others talked about theories, many expressed regret and one wrote indirectly to him.
