Jesse Choper and Daniel Farber quoted by San Francisco Chronicle, May 6, 2017
“If he wants to have a private talk, he ought to have it in his office,” Choper said. He said protesters can’t be allowed to “censor the speaker” by drowning Trump out with shouts, but they should at least be allowed to hold up signs — or Russian flags — as long as they can’t be converted to weapons.
Daniel Farber said he was leery about the willingness by Trump’s lawyers to condone the use of force against protesters. “The state has an interest in preventing violent acts and requiring people to use legal channels,” Farber said. “An abortion protest might violate the rights of a clinic, but that doesn’t mean the clinic people have the right to beat them up.”
