His purpose, judging solely from his behaviour, was disruption. Yr hmbl srvnt would have given, had he been there, very strong consideration to ''interrupting'' him via a pop in the chops.
Police everywhere have a charge (no pun) for third-class jerks such as this, to wit: BNA...being an asshole.
You’re misinformed.
(1) Kerry came to speak and participate in a question/answer session.
(2) The student was waiting his turn at a designated microphone when Kerry invited him to ask his question.
(3) The student took 5 seconds to, pro forma, thank Kerry for coming to speak, and then started asking his question.
(4) 23 seconds later, the police interrupted him, but eventually allowed him to continue.
(5) 45 seconds after that, the police stepped in without warning to forcibly remove him from the auditorium.
You don’t see a problem with that?
More than that. He barged through people to cut the line, interrupted someone else asking a question, and demanded that Kerry answer his questions.
Kerry let him speak instead of tossing him out.
Then he went into a question that really wasn’t a question at all.
He fully deserved it.
