The challenge of "street Spanish" to law enforcement is overwhelming, since dialects are very different and the average teacher of Spanish has not been exposed to street Spanish. In addition, the ratio of Spanish-speaking police officers to the Hispanic population is low. People who speak no English are protected by the same constitutional guarantees as anyone else. This means that delays in the judicial process due to lack of communication place police officers at risk of lawsuit. Teaching materials and vocabulary aids are available to help police officers learn street Spanish.
