Even though there were no cockpit warnings or oxygen masks dropping, he made a steep and fast descent, 27,000 feet in just eight minutes. Passengers on board concerned, calling it a nose dive. They asked us to tighten our seatbelts, and we basically nosedived until we leveled out at 10,000 feet and that was pretty darn scary. Reporter the Buffalo Airport ready for an Emergency Landing.

Reporter this video of the arrest of fredie gray, who died in police custody, doesnt explain his severe spinal injury according the Baltimore Police union. Five of the six officers involved, including the arresting officers have been interviewed. The union says gray was not wearing a seat belt and it believes he was injured not during this arrest, but in the van. Saying they just dont know how. That is not enough for citizens who are pouring out onto the streets. Police brutality is at an alltime high and it just needs to stop. Reporter grays mother collapsed, his sister in tears.

Tonight, in this new police audio tape we hear him explain what went through his mind when he saw that suspect. Holding what i believed to be a locked and loaded rifle, based on the transmission that he shot into the air. There was occupied businesses. Two other officers at the end of the street. This is what i deem at this point to be a lethal force encounter. I have two thoughts that go in my mind. I need to shoot him to stop the threat or that police force defending that officer, saying he had a difficult decision to make. We turn now to boston tonight.

They say it proves he is a cruel character, unconcerned, unrepentant, and unchanged. Deserving of death. But the defense then introducing video of that same moment meant to show tsarnaev in a different light. A 19yearold shuffling around his cell awaiting arraignment, just three months after the bomb bombing. Preening staring right into the camera, flashing the v sign before that gesture. A restless immature teenager. Someone they will argue whose life should be spared. Some of tsarnaevs own victims have already made up their minds about whether he should live or die. Celeste corcoran lost both legs in the last. Her husband, kevin, fastening a tourniquet in the chaos. Now, he wants the bomber executed saying if hes dead no matter how long it takes, end of story. We dont want him to be able to communicate and possibly influence anyone. Other victims like karen and john odom. He lost so much blood, his heart stopped beating twice. They have a different view. We want to see him rot in prison the rest of his life. Were not against the Death Penalty. We just think the Death Penalty is too good for him. David, ultimately, that decision will be made by the 1 jurors. If the defense can convince just one of them to spear tsarnaev he will spend the rest of his life behind bars. David . Ron thanks.
