Your Rights By Cyrus Najmabadi
If government agents question you, it is important to understand your
rights. You should be careful about what you say when approached by law
enforcement officials. If you give answers, they can be used against
you in a criminal, immigration, or civil case.
‘Your Rights’ provides effective and useful guidance in a
user-friendly question and answer format. The application 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.
‘Your Rights’ 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. Source Code Download
