[T]he guidance urges officers to consider a range of nonviolent behavior and common protest gear—like masks, flashlights, and cameras—as potential precursors to violence, telling officers to prepare “from the point of view of an adversary.”

Protesters on bicycles, skateboards, or even “on foot” are framed as potential “scouts” conducting reconnaissance or searching for “items to be used as weapons.” Livestreaming is listed alongside “doxxing” as a “tactic” for “threatening” police. Online posters are cast as ideological recruiters—or as participants in “surveillance sharing.”

One list of “violent tactics” shared by the Los Angeles–based Joint Regional Intelligence Center—part of a post-9/11 fusion network—includes both protesters’ attempts to avoid identification and efforts to identify police. The memo also alleges that face recognition, normally a tool of law enforcement, was used against officers.

Vera Eidelman, a senior staff attorney with the American Civil Liberties Union, says the government has no business treating constitutionally protected activities—like observing or documenting police—as threats.

DHS did not respond to a request for comment.

“Exercising those rights shouldn’t be justification for adverse action or suspicion by the government,” Eidelman says. Labeling something as harmless as skateboarding at a protest as a violent threat is “disturbing and dangerous,” she adds, and could “easily lead to excessive force against people who are simply exercising their First Amendment rights.”

“The DHS report repeatedly conflates basic protest, organizing, and journalism with terroristic violence, thereby justifying ever more authoritarian measures by law enforcement,” says Ryan Shapiro, executive director of Property of the People. “It should be sobering, if unsurprising, that the Trump regime’s response to mass criticism of its police state tactics is to escalate those tactics.”
