Several laws protect civilians against police harassment. These laws are outlined in civil and criminal statutes in the U.S constitution and are applicable to all persons irrespective of their citizenship status, explains the U.S. Department of Justice.
Civil rights laws protect civilians from willful deprivation of any of their rights by a police officer. These laws protect civilians from the use of excessive force during an arrest. They also prohibit police officers from intentionally making a false arrest, intentionally fabricating evidence and sexually assaulting a suspect. Police officers who fail to intervene as a fellow officer violates the rights of a civilian are also liable for prosecution under the civil rights laws described under section 1983 of the Civil Rights Act of 1871, according to FindLaw.
Title VI of the Civil Rights Act of 1964 in conjunction with the Office of Justice Program Statute protects civilians from police harassment and discrimination on the basis of national origin, religion, race and sex. Police officers who use racially abusive language or discriminate against civilians of a particular religion when making an arrest are liable for prosecution, states the U.S. Department of Justice. There are also several administrative remedies that victims of discrimination can pursue.
