Which structure currently operates as a "virtual fence:"  Boarder Wall or Mexico-United States Barrier?
Day Without Immigrants 2017 Day Without Immigrants (or A Day Without Immigrants) was a protest and boycott that took place on February 16, 2017, to demonstrate the importance of immigration, and to protest President Donald Trump's plans to build a border wall and to potentially deport millions of illegal immigrants. The strike called for immigrants not to go to work, to avoid spending money, and keep children home from school. People took part to show the importance of immigrants to the economy and also to protest possible racial profiling of U.S. citizens by immigration enforcement. The strike was planned on social media. People first started talking about the strike after the Women's March, and as the idea gained momentum, important people in the restaurant industry helped boost exposure.
Suicide barrier A suicide barrier is a barrier on a bridge (often a so-called suicide bridge known for suicide attempts), observation deck or other structure designed to prevent people from attempting suicide by deliberately jumping. Many suicide barriers are tall and fence-like. But suicide nets, which extend horizontally below the bridge and preserve views outward, have been used on the Bern Muenster Terrace in Bern, Switzerland and the Cornell University campus in Ithaca, New York. In 2009 a barrier was built for the Humber Bridge, and in April 2017, California began construction on a $200 million mesh barrier beneath the Golden Gate Bridge.
