The decision to charge four friends of the Boston Marathon bombing suspects is facing some criticism as the first trial kicks into high gear.
Some experts say prosecutors have been overzealous in charging the men.
Opening statements are slated for Monday in the federal obstruction trial of Azamat Tazhayakov, a college friend of Dzhokhar Tsarnaev.
Prosecutors say Tazhayakov and another friend removed items from Tsarnaev’s UMass–Dartmouth dorm room several days after the bombings, but he is not accused of taking part in the attacks or knowing about them in advance.
A third friend is charged with lying to investigators, while a fourth is accused of lying about the extent of his relationship and contact with Tsarnaev’s older brother, who died in a shootout with police.
