"and has the backing of one of America’s most prestigious educational establishments"
I'm not sure what relevance his college has to deciding whether or not he is a security threat. The unabomber had a PhD from UC Berkeley, probably the leading public university in the United States, and Dzhokhar Tsarnaev was a student at another fine university in Massachusetts. I would think he should be judged on his personal character, not whether he is smart enough (or as we have recently seen, rich enough) to get into a highly rated college.
Just my personal opinion (I wasn't smart enough or rich enough to get into Harvard).
