From the ACLU:

The ACLU's Know Your Rights booklet provides effective and useful guidance in a user-friendly question and answer format. The booklet addresses what rights you have when you are stopped, questioned, arrested, or searched by law enforcement officers. This booklet is for citizens and non-citizens with extra information for non-citizens in a separate section. Another section covers what can happen to you at airports and other points of entry into the United States. The last section discusses concerns you may have related to your charitable contributions and religious or political beliefs. The booklet tells you about your basic rights. It is not a substitute for legal advice. You should contact an attorney if you have been arrested or believe that your rights have been violated.

This free booklet is available in English, Spanish, French, Arabic, Urdu, and Farsi. An older (2003) version of the booklet is available in Hindi, Punjabi, and Somali. Booklets in these languages are available for download below.
