You have a right to free speech, but that doesn’t give you a First Amendment right to camp out on my lawn with protest signs. That’s trespassing. But government officials sometimes allow trespassing when they sympathize with the trespasser’s viewpoint. The Democratic-run cities of Baltimore, Philadelphia, and Washington, DC have refused to remove progressive anti-Israel protesters camping out at private universities — Johns Hopkins University, the University of Pennsylvania, and George Washington University.

Law professor David Bernstein notes that “Baltimore police will not assist in removing illegal encampment at Johns Hopkins University. Worse, they actually praise the illegal encampment as a valid exercise of First Amendment rights, which is complete nonsense. It’s especially nonsensical because most of the protesters are trespassers with no connection to the university.” “The City of Baltimore strongly stands with every person’s First Amendment rights. Barring any credible threat of violence or similarly high threshold to protect public safety, BPD currently has no plans to engage solely to shut down this valid protest or remove protesters,” said the Baltimore police department in a statement apparently dictated by the mayor’s office. As Professor Bernstein observes,”it’s not the police that are the problem, but the mayor, who has ordered the police to stand down in deference to his primary on Tuesday.”

Contrary to what this statement claims, there is no “First Amendment” right to camp out on public property, much less private property like the campus of Johns Hopkins University, which can tell trespassers to leave regardless of whether they are engaged in First Amendment activity. Camping out on someone else’s property is not a “valid protest,” even if the protesters have not yet made any “threat of violence.” The Supreme Court ruled that protesters do not have a right to camp out even on public property devoted to public use, like national parks, in Clark v. Community for Creative Non-Violence (1984).

Yet Neetu Arnold of the National Association of Scholars notes that Philadelphia is similarly refusing to clear out a protest camp at the University of Pennsylvania, a private Ivy League university: “Philadelphia Police ignores Penn’s request to disband unauthorized encampment. The university has to provide proof that the encampment poses an imminent danger. Penn students have received multiple warnings to avoid the immediate area.” The Daily Pennsylvanian reports that the “Philadelphia Police Department declines to disband encampment after Penn requests immediate help.”
