Easily overlooked in the small print of President Donald Trump's Sanctuary Cities Executive Order signed Wednesday is a clause making it a crime to help an undocumented immigrant.

The Secretary of Homeland Security "shall issue guidance and promulgate regulations ... to ensure the assessment and collection of all fines and penalties ... from aliens unlawfully present in the United States and from those who facilitate their presence in the United States," it reads.

The rule is similar to one that was included in an early draft of Arizona's controversial 2010 anti-immigrant bill SB1070, which proposed making it a Class One misdemeanor to "conceal, harbor or shield" an undocumented immigrant. Class 1 misdemeanors carry a maximum fine of $2,500 and up to six months in jail.

Deja vu

The president was trampling the rights of the people in his use of executive action on Sanctuary cities, according to Falcon. "Now more than ever we have to know our rights, remain silent if you are stopped, be prepared for a raid and have a plan to know what to do in an emergency situation," she added.

SB1070 was the first law of its kind in the country. Among the recommendations included in its original draft, it required local police officers to question or require a person to declare their immigration status.

Public opinion was deeply divided over the law which sparked protests across the country as well as a boycott of Arizona.

It was challenged in the courts by a class action lawsuit, as well as the U.S. Department of Justice and an injunction was granted blocking some of its key elements, including the requirement by police to check the immigration status of those stopped or detained.

The U.S. Supreme Court ruled in 2012 that the offending parts of Sections 3 and 6 of the law were preempted by federal law, including a requirement that all immigrants carry documentation of lawful presence in the country. It upheld a part of the law allowing Arizona police to investigate the immigration status of someone stopped or detained, but only if there was a reasonable suspicion they were not in the country legally.
