Yes. A probably mentally disturbed person, who had been with the protestors for days (and reportedly been asked to leave by the protesters for his erratic behaviour) fired several shots into crowd killing 1 and injuring at least one more (who may have been shooter) The news article I read said several people pulled weapons, and police were trying to figure out who shot where, which leads me to think that several oeople fired back at this deranged guy.
Police arrived 4 minutes later.
When seconds count, police are minutes away.
