Don’t Ban Masks At Protests

Most Boston ICE protesters know to mask up. The rest, we blur out for their safety.

It’s hearings season at the State House, so this is when we put together testimony on bills that particularly relate to privacy, surveillance and the Fourth Amendment. But first, a little history on the issue of face masks and privacy.

Before wearing a surgical mask became politicized as “a thing woke liberals do,” the Boston police, in fall 2019, tried to criminalize the wearing of masks in public without criminal intent. We objected, and testified in masks, because wearing a mask shouldn’t give discretion to police to launch in and arrest you. For some reason, though, by the spring of 2020 nobody was interested in banning mask-wearing.

In 2023-25, as the pandemic receded, and in response to the Gaza ceasefire protests, elected officials also began dusting off mask bans as a way to signal that they, too, found such protests unacceptable. Most notably, Gov. Hochul of New York, citing anti-semitism concerns tried hard to revive a ban (Our national coalition joined NYCLU in opposing it). Police would love these bans to pass, because it’s a lot easier to identify people if they’re not wearing masks, whether you use facial recognition software or not.

Most recently, the Trump administration is trying to require both universities and local governments to hand over drone and camera data of protests, presumably so that the administration can then use facial recognition software to identify unmasked people engaging in disfavored activities as well as crimes. In the Los Angeles area this week, the federal government has directly intervened to conduct aerial surveillance of protests using drones, and connectedly, President Trump posted on June 5 on Truth Social, “From now on, MASKS WILL NOT BE ALLOWED to be worn at protests. What do these people have to hide, and why???”

Inappropriate aerial surveillance of protesters may escalate still further, into violence. Regarding this coming weekend’s military parade in DC, the President has threatened any protesters with “heavy force.” Abroad, U. S. military drone technology has already been used in attacks on weddings, funerals and hospitals. Even domestically, lethal extrajudicial attacks on members of disfavored groups and people accused of violence are not unknown. The guardrails intended to protect us at home from our own government are getting weaker. The new facial recognition and AI-based targeting capabilities of military technology mean that today’s protesters face risks of identification that previous generations of protesters did not. The First Amendment, of course, ought to restrain the President from escalating further; but he already has a track record of only refraining from violating the law, where he faces a realistic chance of personal legal or financial consequences. Who among us can be fully confident that he will rein himself in?

Our own organization has always been explicitly peaceful and law-abiding, but even peaceful people have an interest in being able to protest or just to move around in public, without having their facial features fed into a federal facial recognition algorithm for them to be investigated as an opponent or dissenter and “doxxed”, “swatted”, harassed or prosecuted. Both the Supreme Court and Massachusetts’ Supreme Judicial Court have now recognized that people have a privacy interest in the pattern of their movements in public. So we have good grounds for saying that masks are an important tool for the privacy-conscious.

To sum up, people can have perfectly valid reasons for masking, even if they have no health conditions that a mask would help with. Because of the risks to people’s privacy alone, we should not in any municipality in Massachusetts, at any point, be requiring people to unmask in public. We strongly support a favorable report for S. 1427‘s ban on municipal or board of health measures that prohibit “the wearing of face coverings for protective or medical use in any indoor or outdoor space open to the public.”

Mr. Anderson’s Rough Guide to Anonymous Protest

B4D45GpCMAEixpp.jpg:large

Note: These methods are not foolproof. Even if you take every precaution described below, you should still assume that you are being watched, tracked, and recorded. Act accordingly.

I. Leave your cellphone at home. It is safe to assume that “Stingrays” (also known as “cell site simulators” or “IMSI catchers”) are being used at every #BlackLivesMatter protest around the country. These devices trick your phone into connecting to them by simulating a cell tower, allowing law enforcement to intercept your text messages and phone calls as well as your location information and International Mobile Subscriber Identity (your phone’s unique identifier). They are small enough to be mounted on vehicles and can even be placed on airplanes and helicopters to track protesters from the sky. It is probably best to leave your cellphone at home. If this is impractical for you, you might want to consider using secure messaging apps such as Wickr or TextSecure. Note that as long as your phone is turned on, your location information and IMSI information can still be intercepted.

II. Avoid exposing your face to cameras. Police love to video record protesters exercising their First Amendment rights. Unless you want to run the risk of having images of your face uploaded to a network of shadowy databases to be matched with driver’s license photographs and other government records for tracking purposes, it is wise to consider covering up your face or applying face paint in a manner that prevents facial recognition software from identifying you. Some believe covering your face is cowardly, but if the choice is between being indexed in a virtually boundless, unaccountable surveillance system and the right to protest anonymously without retribution, I’ll take the latter any day.

III. Avoid advertising your location or other personal information on social media. Fusion centers and police departments like to track people using social media geolocation software to track social media posts in real-time. This is likely one of the tools used by the Massachusetts fusion centers for tracking #BlackLivesMatter protesters in Boston. You may want to avoid using social media altogether while at a protest; but if you feel the need, it might be a good idea to create a fake account to make it a little more difficult for spies to monitor you.

IV. Use PGP for encrypted emails. Encryption is your friend. “PGP” stands for “Pretty Good Privacy”, and it holds true to its name. Think of PGP as an airtight container that keeps your emails away from the eyes of anyone except the intended recipient(s). Sure, it can be a little tough to set up, but once you have it installed, it’s actually very easy to use.

Here is a guide to installing PGP for Mac OS X.
Here is a guide to installing PGP for Windows and GNU/Linux.

V. Use Tor and/or a VPN. Tor is free software that provides anonymity by routing your Internet activity through a series of other users running Tor relays. The goal is to prevent eavesdroppers from seeing the web pages you visit by bouncing your connection around the network, making it appear as if you are accessing the Internet from a completely random location. Similarly, Virtual Private Networks route your connection through a server of your choice, making it appear as if you are connecting to the Internet from France, Canada, Sweden, or pretty much anywhere. Unlike Tor, good VPNs are not free, but they can be as inexpensive as $3.33 per month.
