The Seed of a US Gestapo

At Balloon Juice, in response to an exceptionally cruel action by Customs and Border Protection, John Cole comments: "ICE and our Border Patrol are now effectively the brown shirts for this regime. Treat them as such." 
  More the seed of a Gestapo, I think, the seed of a national secret police, than brownshirts (SA), Nazi paramilitaries, I think. It’s a little more than a pedantic point: the Gestapo had official power; the SA were party thugs and were ultimately suppressed by the Nazi leadership. The Gestapo was created by unifying the police forces of the Reich under the SS. The US analog of this would perhaps be bringing state and local police forces with ICE which, indeed, is being attempted.
