It boils down to a simple question: If you accept legalization for the undocumented as desirable and inevitable, then why continue to put them through hell?

As they wait for a legalization bill, they are suffering under unjust laws, corrupt policing and a detention and deportation system that routinely suppresses their rights. American citizens who are Hispanic, and are all too frequently victims of racially-driven sweeps, are also suffering. Mr. Obama and his Homeland Security secretary, Janet Napolitano, must do much more to curb those excesses.
