>let people break the law, because they are economically beneficial

Doesn't sound very humanistic to me, especially if you think who benefits the most from their unregulated labour.

While having secret police running around and forcing their way without any discretion is quite bad and ill omen for the future, it doesn't eliminate all the problems that are brought with illegal immigration (and even legal one as well). One could argue, that this ICE showdown is a reaction to almost pathological leniency before, when people in need were used as economical benefits for the rich, as it was mostly them that benefited from employing illegally all those workers, while unloading all nasty side effect on the common folk.
