"We don't deny that Jahar fully participated in these events. But if not for Tamerlan" they would not have happened.

"Dzhokhar Tsarnaev stands ready by your verdict to be held responsible for his actions."

What does any of this matter if we know #Tsarnaev carried the bomb down Boylston? It matters because you are entitled to know the full picture, Clarke says.

#Tsarnaev's tweets that seem ominous came from rap lyrics, from comedians, from poems. That's not a jihadi in the making, she says.

Let's look at #Tsarnaev's browsing history; he went to Facebook and VK (Russian Facebook) "This is a kid doing kid things."

"We do not deny that he had these extremist materials on his computer, but he's be honest about how prominent they were in his life & when."

"Let's be honest about what the evidence actually shows. We are not asking you to excuse the conduct."

"You know who made these bombs; it was Tamerlan."
Tamerlan was the leader, Jahar the follower. But for Tamerlan, these bombings would never have happened. Tamerlan bought all the ingredients. Tamerlan killed the officer. This is the theme the defense will focus on in closing, in an attempt to get a life sentence.

"It was Tamerlan who bought the pressure cookers."
Dzhokhar was in Dartmouth; There were no bomb-making instructions on Dzhokar's computer.

Tamerlan did the research, he had the Russian-language translation of the Inspire bomb-making docs.

Tamerlan alone talked to Dun Meng, you remember that. Tamerlan led, and Jahar followed.

It "is simply not true" that #Tsarnaev self-radicalized. The evidence is Tamerlan built bombs and Tamerlan killed Collier.
