ALT Naturally, the purpose of DHS agencies like ICE is to arrest people for no reason. Federal agents, working with local cops, have disappeared thousands of migrants through mass deportation, sometimes leaving them to face the gang violence they originally fled. DHS breaks up families and even funnels children into the foster system to be adopted. Matching this federal form of ethnic cleansing is everyday urban policing, where for decades plainclothes units have been snatching people off the street in anti-gang operations, frequently leading to violent reprisals because it is unclear whether the state or "opps" made the snatch. The echoes of Argentina's "dirty war" are clear.
