What happens now
Cory Gnazzo, senior producer of the Rachel Maddow Show, shares a preview of tonight’s show – on the Monday after the arrest of one of the suspects in the Boston bombings last week, we’ll take a look at the direction of the investigation and what has come out since the suspect’s arrest; plus, a look at how Boston has dealt with the tragedy and how the diligent and difficult work of doctors and medical personnel saved many lives last week; and we end on a scientifically sweet note.
