Some might say one of the most important ways we exercise the right to free expression is through protests. And we’ve certainly seen groups all over the world using that right in the last few years, from the George Floyd protests in the U.S. to democratic marches in Hong Kong to demonstrations in Chile, Venezuela, Iran and Peru.

On the surface this right may seem straightforward, but there are many thorny questions to grapple with: when does a protest become a violent violation of other rights, what does it mean to protest in the age of surveillance, does the content of the protest matter for it to be protected?
