Does someone comment on whether an expansion of DHS authority is in progress? Should the Justice Department be involved? I didn't know they could raid domestic businesses and seize property, but it's very possible I was ignorant of it. I wonder because of another story, in which ICE (Immigration and Customs Enforcement, part of DHS) raided a website that provided ads for prostitution. ICE made this claim in the article: As the investigative arm of the Department of Homeland Security, ICE is responsible for the enforcement of laws that promote the legitimate movement of people, goods and currency in domestic and foreign transactions. Our allegation with this case is that the business and its principals purported itself to be an escort service while promoting criminal acts, namely illegal prostitution. The movement of "people, goods, and currency" sounds like a very wide remit, covering almost every economic transaction, any time someone takes a step on the sidewalk, and more. In fact, it sounds like they stretch even that to cover prostitution. https://www.nytimes.com/2015/08/27/nyregion/raid-of-rentboy-an-escort-website-angers-gay-activists.html https://www.nytimes.com/2015/08/27/nyregion/raid-of-rentboy-...
