I’ll respond to the UCB event I am familiar with. At first, I was also puzzled by the lack of police activity, but later learned the campus police were not prepared for the violence by non-student Antifa perps.
Your reference also indicated:
Dan Mogul, assistant vice chancellor and spokesman for the UC Berkeley, said that administrators at Berkeley intend to protect First Amendment rights, but may need to more closely examine certain events if they have the potential for disruption and damage on campus. “It’s not about limiting free speech,” he added, but about the security of the campus.”
Will Trump increasing funding to universities to host these events requiring more security?
