A prime FBI informant against protesters at the Republican National Convention has waived the right to his own trial:

An undercover FBI informant who infiltrated an anarchist group planning disruptions at the Republican National Convention waived his right to a trial on Monday for an unrelated incident in which he is charged with five counts of assault, burglary and damage to property.

Information from the informant—Andrew Darst—is being used against the RNC 8, who will stand trial for criminal conspiracy to disrupt the Republican National Convention in St. Paul. He's waiving his trial, presumably, because is own criminal case (and the public airing of its details) could undermine his credibility as a witness.

His own crime?

On Jan. 11, Darst was arrested for breaking down a door and entering a house in Minnetrista and assaulting two men around 2 a.m. He told police he was "wasn't comfortable with the people his wife was with there." According to the police report, Darst struck two men.

Sounds like this star witness and undercover informant has got some issues.
