the people who helped organize this reminded me of a quote from justice kennedy in the arizona litigation, the arizona versus united states litigation from 2012. and it's not about sanctuary cities at all. but it's a very good device to help set the stage for us in the discussion we hope to have this morning. so high kick it off with this. in talking about the relationship between state policing and federal immigration enforcement, justice kennedy wrote, "the sound exercise of national power over immigration depends on the nation's meeting its responsibility to base its laws on a political will informed by searching, thoughtful, and rational civic discourse." so we begin this panel with that goal in mind, to facilitate a searching, thoughtful, and rational civic discourse on the subject of where national immigration authority interacts with state policing. with that, i'm going to turn to michelle's opening presentation. >> great. thank you so much, karen. and thank you so much to the aba for inviting me to be part of this panel this morning. my job was to present an overview and the basics so we could get this conversatio
