DHS is a security, not LE, agency, and security agencies are in the business of protecting the State, not little old you. DHS agency in particular does so from domestic (read citizen) threats. Apparently, typically "white" constitution reading, gun buying folk are getting on their nerves. According to government critters, when people of a certain race get angry, they riot. When people of another race get angry, there is revolution... you do the math. Of course that´s just my own interpretation of their .gov thought process, attempting to explain the "kill whitey rhetoric".
