The Women's Marches last weekend were collectively some of the largest protests ever conducted in the United States. While we would love to have some hard data to be able to inform the public about what type of surveillance being used on the demonstrations, unfortunately many of the police department's we have requested in our Cell Site Simulator Census have either not given us any documents yet, or used sweeping law enforcement exemptions in order to not disclose some of the more sensitive, and important, information about their use.
