This link. "Abolish ICE" seems an easy cry, while reforming it is tepid but sensible. Customs enforcement needs a home. Beyond that, the "Abolish ICE" creed conveniently ignores reforming the entire sorry, stupid Patriot Act, where reform has been ignored far too long.
ICE abolition is a misdirection effort, so why go there when reform of the so-called Patriot Act howls for attention, except in mainstream media.
