To ask the question is to answer. Somehow, the USA managed to exist for 200 years without the DHS.

In early June, after the killing of George Floyd, when tens of thousands of mostly peaceful demonstrators assembled in cities across the country to protest police brutality, the Department of Homeland Security sent hundreds of its agents to patrol the crowds. They cleared space for a Presidential photo op in front of St. John’s Church, in Washington, D.C., by forcibly removing demonstrators, and in New York City they reportedly made at least one arrest at gunpoint. The legal rationale for their being on the scene was a statute from 2002 that gave them broad authority to protect federal property and personnel. This mandate sounded just vague enough to escape mainstream notice at the time, when police officers were being filmed tear-gassing and beating protesters. But a pressing question remains, which the D.H.S. leadership can’t easily answer: What are agents from Customs and Border Protection and Immigration and Customs Enforcement doing in the streets of U.S. cities nowhere near the border, policing citizens who have broken no laws?
