Know your rights!
It’s important to know your rights, and how to exercise them.
The ACLU has a page dedicated to this topic, https://www.aclu.org/know-your-rights, that covers a number of different situations, and what your rights are in each situation, such as:
LGBTQ rights
Immigrants’ Rights
Students’ Rights
Voting Rights
Stopped by Police
Religious Freedoms
Health Care Providers
And many more…
You can also keep on hand a Know Your Rights card (also known as a Red card).
You can print these out at home using this link: https://www.ilrc.org/sites/default/files/documents/red_card-self_srv-english.pdf
Educating yourself is critically important so that if a situation arises, you can remain calm, stay safe, and protect yourself and others to the best of your ability.
