came to me in an e-mail:

As you come out to protest, here's what our video notes to keep in mind:

1) The right to protest is a fundamental human right guaranteed by the U.S. Constitution and the First Amendment.

2) If you get stopped, ask if you are free to go. If the police say yes, calmly walk away.

3) You have the right to record. The right to protest includes the right to record, including recording police doing their jobs.
