Carmen Ortiz, the embattled U.S. attorney who charged the late activist Aaron Swartz with multiple felonies, has responded to critics by saying complaints about any prosecutorial overzealousness are "inaccurate" and "unfair."

Ortiz, 57, said in a radio interview that a wave of criticism -- which includes a congressional investigation, a court Web site hack, and a petition demanding her removal from office -- is off-base and uninformed. ...

WBUR and Massachusetts Lawyers Weekly published a joint report into Ortiz's tenure that found "other prosecutions that parallel the Swartz case" that may "raise similar concerns about her hands-off leadership style, overzealousness, judgment and use of discretion at the grand jury and trial levels." In one case Ortiz's office brought, a federal judge threw out the charges against a defendant after declaring prosecutors' witnesses were so unbelievable that no jury would find them credible. In another, prosecutors accused a medical device company of defrauding surgeons but never talked to the alleged victims, who were prepared to testify for the defense.
