Citing a senior Congressional aide, the Los Angeles Times reported last week that Tsarnaev "asked several times for a lawyer, but that request was ignored."
A Justice Department spokesman declined to comment on that claim or to discuss the agency's policy on that point. An FBI spokesman did not respond to an inquiry on the issue.
The first case cited in the FBI-published article is a 1989 ruling from the 9th Circuit in which a convicted heroin dealer asserted he'd asked for a lawyer before he told inquiring U.S. Marshals that he had a gun in his home.
