So what is the Justice dept saying the state of Arizona is doing different from what a federal agent would also do. As an example during a raid on any business, don’t they ask all employees to show documentation of citizenship?
This is such a specious argument.
ICE has been totally undercut in this capacity. Even before Obama showed up in order to do a work place enforcement you had to build a case and get warrants. Despite what the left whines about, ICE doesn't just say "Hey, let's go raid the tortilla bakery." They have to do a lot of case work to get there.
