I don't know whether he is the culprit or not, but what is circulating this photo in our discussion environment.
he was not some random student, faculty, visitor watching the debate. you can clearly see he is on the inside of the area, thus part of the entourage so would have been vetted and checked by security
I don't see him as a potential suspect even if others do since he's top was not similar to that of the suspect.
before anyone knew the killers name or description. some spotted this guy in blue shirt and noticed something in his hand and just alleged he might be a suitable suspect/man of interest. and even now people still are wondering about this guy and what was in his hand
i simply expelled some notions by just bringing attention to the fact of which side of the barrier he was on, to say he is not part of the random crowd. he seems to be one of the vetted/checked entourage allowed to be on the inside of the barrier. so im sure he was exonerated as not a suspect
obviously video footage would also show the direction and type of killshot was not of one from a close proximity of a small weapon
