So what happens if they extract confessions and all sorts of other information without Mirandazing him then realize none of it can be used in a trial?
They have other evidence. But I saw on CNN a couple hours ago that they may not arraign Dzhokhar Tsarnaev today at any rate because he may not be able to talk. That is because of the gun shot wound he suffered to the neck. So he is apparently not talking. He may also be heavily sedated due to the surgeries he undoubtedly had for his gun shot wounds.
Two other things about Dzhokhar Tsarnaev:
In the initial confrontation with police his older brother was shooting at cops and they were shooting back. According to Watertown Mass Police Chief Ed Deveau, the older brother, Tamerlan Tsarnaev, ran out of ammunition and then charged at officers. Several of the officers tackled him, took him to the ground and attempted to handcuff him. While this was going on the younger brother, Dzhokhar Tsarnaev, got behind the wheel of the stolen SUV and drove head-on at police. The officers subduing Tamerlan Tsarnaev, jumped out of the way but Tamerlan Tsarnaev was run over by his brother, and dragged a short distance down the street. Chief Deveau said that they, police, believe that was what killed Tamerlan Tsarnaev, he was run over by his brother. (The doctors at the hospital where he was taken said he died of cardiac arrest.)
The other thing is, some of the police interviewed said they were struck by the fact, the brothers apparently had "no endgame." They planned the attack, made the bombs, acquired the backpacks, etc. What then? What were they going to do AFTER the bombing? Did they just assume the police would be unable to figure out who did it?
In line with this, I keep wondering about Dzhokhar Tsarnaev lying under the tarp in the boat in the back of a Watertown house on Friday. What was his plan? He was alone. He had no food, no water, no transportation. He was seriously injured. He apparently lay in the boat hour after hour like an injured animal. What was he going to do next? In fact, if the homeowner had not discovered there was someone in the boat, in all likelihood, Dzhokhar Tsarnaev would've bled to death overnight.
There are reports Dzhokhar Tsarnaev went to college classes on Tuesday, the day after the bombing, and even went to a party that night.
Very strange episode.
