Day 3: When Marathon Bombing victim Jess Kensky took the witness stand last Monday at U.S. District Court in Boston, she testified about  her experience the day the two bombs went off at the finish line in April 2013. Kensky lost both her legs from the bombing and has had 20 surgeries.

Boston College Law Professor Robert Bloom says  the prosecution, in its opening statement, was trying to put the jurors at the scene of the crime.  Bloom says, "hearing the testimony, showing the awful injuries that occurred, and  the heroism displayed by police and public safety personnel, shows the courage they took in risking their lives to remove the injured away from the scene."

Bloom says the defense attorney’s strategy during cross examination, Judy Clark posed the question of how Tamerlan Tsarnaev was leading his younger brother, the defendant, onto Boylston Street the day the bombs went off.

Professor Bloom says Clark is seeking to demonstrate the older brother’s influence on  Dzhokhar and that he was  following his older brother.

According to Bloom, http://www.bc.edu/schools/law/fac-staff/deans-faculty/bloomr.html, the twitter accounts introduced  by the prosecution is meant to demonstrate that he was Islamic terrorist, and not someone posting religious tweets mixed with social chatter.

Tsarnaev Boat Writings Show Defendants State Of Mind

Day 4: The trial of admitted Boston Marathon Bomber Dzhokar Tsaraev took another dramatic turn  Tuesday when a Boston Police officer testified in U.S. District Court about searching the boat where Tsarvaev was hiding and ultimately captured by police in Watertown on April 19,2013.

Inside the boat were writings that Tsarnaev had scribbled in pencil with references to his Islamic faith and permission to kill innocent people in defense of other Muslims according to the witness.

Northeastern University Law Professor Daniel Medwed who has expertise in the area of criminal law and is a renowned scholar on wrongful convictions, says the "writings are very important to the prosecution because they show Tsarnaev's  state of mind in the aftermath of the crime."

He says the reason why the defense wants to introduce the whole boat is because," it provides context for Tsarnaev actions, and shows he acted under the influence of his older brother, Tamerlan Tsarnaev. According to Medwed, the defense theory showing jurors the life-sized boat, gives the whole picture ...the bullet riddled boat, and all of the panels inside where he was hiding... demonstrates that Tsarnaev acted under the shadow of his brother, and not in a clear state of mind."

Tsarnaev Defense Seeks To Challenge Prosecutions' Credibility

Day 5: It’s difficult to determine if the defense strategy to spare admitted Boston Marathon Bomber Dzhokhar Tsarnaev the death penalty is working, but  Northeastern University Law Professor Daniel Medwed says it’s a sound strategy.

He says the case for the defense, “is premised on a broader context to the story and that he was  under the influence of his domineering older brother. However, he adds Judge George O’Toole is limiting the defense attorney's ability to develop that theory during the guilt phase.”

Medwed says the defense is pointing out the flaws in the technology,  suggesting that Tsarvaev’s twitter account had a number of postings, not just Jihadist religious postings, but some relating to girls and other teenage pursuits.

Medwed says the Tsarnaev's attorneys' are seeking to demonstrate the cell phone was used for many other things and that allows the defense to go after technological evidence, and  pursue its strategy without engendering animosity from jurors.

According to Medwed, testimony from a prosecution witness, a Massachusetts Institute of Technology graduate student, who says he observed the defendant  leaning into the police cruiser of an  MIT officer who was fatally shot in April 2013,  shows important post-bombing narrative and "consciousness of guilt."
